--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:5a32e85810d33dc46b1b5fe2803ee787d40709d5 commit r15-9420-g5a32e85810d33dc46b1b5fe2803ee787d40709d5 Author: Jakub Jelinek <ja...@redhat.com> Date: Mon Apr 14 10:18:13 2025 +0200 driver: On linux hosts disable ASLR during -freport-bug [PR119727] Andi had a useful comment that even with the PR119727 workaround to ignore differences in libbacktrace printed addresses, it is still better to turn off ASLR when easily possible, e.g. in case some address leaks in somewhere in the ICE message elsewhere, or to verify the ICE doesn't depend on a particular library/binary load addresses. The following patch adds a configure check and uses personality syscall to turn off randomization for further -freport-bug subprocesses. 2025-04-14 Jakub Jelinek <ja...@redhat.com> PR driver/119727 * configure.ac (HOST_HAS_PERSONALITY_ADDR_NO_RANDOMIZE): New check. * gcc.cc: Include sys/personality.h if HOST_HAS_PERSONALITY_ADDR_NO_RANDOMIZE is defined. (try_generate_repro): Call personality (personality (0xffffffffU) | ADDR_NO_RANDOMIZE) if HOST_HAS_PERSONALITY_ADDR_NO_RANDOMIZE is defined. * config.in: Regenerate. * configure: Regenerate.
