           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.

There is no problem with GNU as.
