http://bugzilla.opensuse.org/show_bug.cgi?id=1048495 Bug ID: 1048495 Summary: GCC 7 causes segfault illegal instruction in glibc with sse instructions using misaligned data on AMD Ryzen Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: jon@moozaad.co.uk QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Ref arch bug report https://bugs.archlinux.org/task/54136 0xf7a247c3 in __strspn_sse42 () from /lib/libc.so.6 The rest of the back trace is irrelevant as it's caused by misaligned data according to the arch BR. Glibc Version : 2.25-2.4 Workaround compile flag is -mstackrealign at cost of performance. Not sure if GCC or Ryzen bug. I am trying to test a specific znver1 build but having trouble getting obs not to error with illegal instruction (irony). Reproduction: run civ 5 or borderlands 2 on tumbleweed - it errors when loading the pulse audio config, same as the arch report. -- You are receiving this mail because: You are on the CC list for the bug.
