Summary: Many 32-bit 30_threads execution tests fail on Solaris
10+/SPARC with as
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ro@gcc.gnu.org
CC: ebotcazou@gcc.gnu.org
Host: sparc-sun-solaris2.1[01]
Target: sparc-sun-solaris2.1[01]
Build: sparc-sun-solaris2.1[01]
Many 32-bit 30_threads libstdc++ execution tests fail on Solaris 10 and
11/SPARC
with Sun as. An example is
FAIL: 30_threads/async/42819.cc execution test
The test SEGVs like this:
Program received signal SIGSEGV, Segmentation fault.
