--- Comment #3 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> ---
So, it seems Matthias is right, there is definitely a regression in gcc-4.9 in
the code generation. Packages that were recently build with gcc-4.9_4.9.2-20 or
newer tend to segfault.
I noticed this with systemd, for example on tirpitz:
systemd_220-2 works fine (compiled with gcc-4.9_4.9.2-10):
root@tirpitz:~/systemd-test> journalctl --version
systemd 220
+PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP
+GCRYPT -GNUTLS +ACL +XZ -LZ4 -SECCOMP +BLKID -ELFUTILS +KMOD -IDN
root@tirpitz:~/systemd-test>
systemd_220-6 segfaults (compiled with gcc-4.9_4.9.2-20):
root@tirpitz:~/systemd-test> ./systemd/bin/journalctl --version
systemd 220
+PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP
+GCRYPT -GNUTLS +ACL +XZ -LZ4 -SECCOMP +BLKID -ELFUTILS +KMOD -IDN
Segmentation fault
root@tirpitz:~/systemd-test>
Attaching the strace for this segfault if that could be in any way helpful.
