A quick analysis showed that this regression was introduced by the switch to gcc-15
in 2.42-6. Building the current 2.42-11 package with gcc-14 works fine.

Not sure whether it's a bug in gcc or glibc, but I reported it to glibc for now [2].

control: reassign -1 src:gcc-15

The upstream bug report mentions it's related to GCC-15 and closed the
bug accordingly. Reassigning the bug to src:gcc-15 on the debian side.
