Comment 4 for bug 809768

Can you capture a core and get a backtrace with gdb? And test with -O0 to see if the SEGV goes away? I have encountered a segfaulting null-pointer-reference optimizer bug in fold_stmt_1(), which I haven't filed yet (the testcase is almost 80K lines and probably not something I can post publicly as-is) but have worked around.
