Source: gcc-11 Version: 11.5.0-3 Severity: normal Tags: patch Dear Maintainer,
gcc-11 11.5.0-3 fails to build with installed gcc-11. See: https://buildd.debian.org/status/fetch.php?pkg=gcc-11&arch=hppa&ver=11.5.0-3&stamp=1756753356&raw=0 The problem is gcc-11 was not upgraded to generate GNU_STACK notes before the release branch was closed. As a result, modules require an executable stack in gcc-11 and earlier. glibc 2.41 no longer allows modules or shared libraries requiring an executable stack to be loaded with dlopen. This broke gcc-11 11.5.0-2. We need to patch gcc-11 to enable the generation of GNU_STACK notes. I manually built and uploaded 11.5.0-3 using glibc 2.40 and the attached patch to generate GNU_STACK notes. The attached patch will need be added to debian/patches if gcc-11 ever needs rebuilding on hppa.
