Created an attachment (id=4248)
 --> (http://llvm.org/bugs/attachment.cgi?id=4248)
a crashing bitcode file

After a period i could not build clang/llvm (rtti changes) i have the problem
that clang (or more correct llvm) crashes on code generation.

Today i build myself a fresh clang/llvm again at TOT r96486 and i bugpoint
reduced the case, please see the attachment:

$ llc bugpoint-reduced-simplified.bc
Stack dump:
0.      Program arguments: llc bugpoint-reduced-simplified.bc
1.      Running pass 'X86 DAG->DAG Instruction Selection' on function
'@handle_accept_in'
segmentation fault
$
