Bug ID: 18694
Summary: sparc sigaction change for glibc-2.20 broke ABI for
sparc32
Product: glibc
Version: 2.20
URL: https://bugs.gentoo.org/550836
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: davem at davemloft dot net
Reporter: vapier at gentoo dot org
CC: drepper.fsp at gmail dot com
Target Milestone: 2.22
Host: sparcv9-linux-gnu
after upgrading Gentoo from glibc-2.19 to glibc-2.20 on sparc, we started
seeing lots of spurious errors from bash like:
configure: line 471: wait_for: No record of process 0
bisecting it back found this sparc commit:
https://sourceware.org/git/?p=glibc.git;a=commit;h=a059d359d86130b5fa74e04a978c8523a0293f77
on a 32bit system, sizeof(long) == sizeof(int) which means sigaction grew by 4
bytes and shifted sa_flags/etc... down.
