Dear Maintainer,

Since version 3.12.0-4, the build fails on hppa.  See:
https://buildd.debian.org/status/fetch.php?pkg=lapack&arch=hppa&ver=3.12.1-4&stamp=1753202248&raw=0

The build fails here:
# Run CBLAS tests, output the result, and stop if one test fails
LD_LIBRARY_PATH=$(pwd):$LD_LIBRARY_PATH /usr/bin/make -C CBLAS/testing run BLASLIB="../../libblas.so" CBLASLIB=""

The attached patch skips the problematic code.

Thanks for the report.

However note that the patch is not ready to be applied, because it
disables the tests on all architectures, and not specifically alpha and
hppa.

We believe that the bug you reported is fixed in the latest version of
lapack, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1110956@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
