[This bug is NOT targeted to the upcoming trixie release] Please keep this issue open in the bug tracker for the package it was filed for. If a fix in another package is required, please file a bug for the other package (or clone), and add a block in this package. Please keep the issue open until the package can be built in a follow-up test rebuild. The package fails to build in a test rebuild on at least amd64 with gcc-15/g++-15, but succeeds to build with gcc-14/g++-14. The severity of this report will be raised before the forky release. The full build log can be found at: http://qa-logs.debian.net/2025/02/16/amd64exp/pypy3_7.3.18+dfsg-2_unstable_gccexp.log.gz The last lines of the build log are at the end of this report. To build with GCC 15, either set CC=gcc-15 CXX=g++-15 explicitly, or install the gcc, g++, gfortran, ... packages from experimental. apt-get -t=experimental install g++ GCC 15 now defaults to the C23/C++23 standards, exposing many FTBFS. Other Common build failures are new warnings resulting in build failures with -Werror turned on, or new/dropped symbols in Debian symbols files. For other C/C++ related build failures see the porting guide at http://gcc.gnu.org/gcc-15/porting_to.html [...] gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Objects/setobject.o Objects/setobject.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Objects/sliceobject.o Objects/sliceobject.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Objects/stringobject.o Objects/stringobject.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Objects/structseq.o Objects/structseq.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Objects/tupleobject.o Objects/tupleobject.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Objects/typeobject.o Objects/typeobject.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Objects/weakrefobject.o Objects/weakrefobject.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Objects/unicodeobject.o Objects/unicodeobject.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Objects/unicodectype.o Objects/unicodectype.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Python/_warnings.o Python/_warnings.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Python/Python-ast.o Python/Python-ast.c gcc -c -fno-strict-aliasing -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/pypy3-7.3.18+dfsg=. -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -Wdate-time -D_FORTIFY_SOURCE=2 -DPy_BUILD_CORE -o Python/asdl.o Python/asdl.c In file included from Include/Python-ast.h:3, from Python/Python-ast.c:13: Include/asdl.h:9:15: error: cannot use keyword ‘false’ as enumeration constant 9 | typedef enum {false, true} bool;
