           Summary: libgo assertion failure in thread.c:40/63 on Solaris 2
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
        AssignedTo: ian@airs.com
        ReportedBy: ro@gcc.gnu.org
              Host: i386-pc-solaris2.11
            Target: i386-pc-solaris2.11
             Build: i386-pc-solaris2.11


Both in the go and libgo testsuites, a couple of testcases randomly fail like
this:

FAIL: go.test/test/chan/powser2.go execution,  -O2 -g 
/vol/gcc/src/hg/trunk/local/libgo/runtime/thread.c:63: libgo assertion failure
/vol/gcc/src/hg/trunk/local/libgo/runtime/thread.c:40: libgo assertion failure

I found that at that time sem is completely empty, so either it hasn't been
initialized yet or already destroyed.  Don't yet know which.
