Created an attachment (id=4126)
 --> (http://llvm.org/bugs/attachment.cgi?id=4126)
One of my compiler unit tests (bitcode file)

With the attached .bc file, opt will run fine with no passes specified, but
will segfault if -O1 is specified.

/home/talin/Projects/llvm-inst/bin/opt -O1 test/stdlib/SwitchStmtTest.bc >
/dev/null
Stack dump:
0.      Program arguments: /home/talin/Projects/llvm-inst/bin/opt -O1
test/stdlib/SwitchStmtTest.bc 
1.      Running pass 'Function Pass Manager' on module
'test/stdlib/SwitchStmtTest.bc'.
2.      Running pass 'Module Verifier' on function
'@"main(tart.core.String[])->int32"'
Segmentation fault
