Bug #: 53284
Summary: Several libatomic tests fail on 32-bit Solaris/x86
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r...@gcc.gnu.org
CC: r...@gcc.gnu.org
Host: i386-pc-solaris2.9, i386-pc-solaris2.1[01]
Target: i386-pc-solaris2.9, i386-pc-solaris2.1[01]
Build: i386-pc-solaris2.9, i386-pc-solaris2.1[01]
With the libatomic build problems on Solaris out of the way, there remain a
couple
of testsuite failures for the default 32-bit multilib:
FAIL: libatomic.c/atomic-compare-exchange-4.c execution test
FAIL: libatomic.c/atomic-exchange-4.c execution test
FAIL: libatomic.c/atomic-load-4.c execution test
FAIL: libatomic.c/atomic-op-4.c execution test
FAIL: libatomic.c/atomic-store-4.c execution test
FAIL: libatomic.c/generic-2.c execution test
It seems all of them SEGV, e.g.
Program received signal SIGSEGV, Segmentation fault.

Seems to be infinite recursion.
