           Summary: sse pthread segfault
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: justin at nurbana dot cx

When executing code with sse intrinsics from a posix thread the program will
crash.  I believe there is a byte alignment issue with glibc or gcc where it's
only aligning 8 bytes instead of 16, which is what sse wants.  I've compiled the
sse multi-threaded code with the intel compiler and it works fine.  My sse code
not using pthreads also works fine under gcc.
