Hi,all
I ran my generated whole-program bitcode file which performs as a bodytrack
tool, it can give me the right result but with a stack dump before it exsits
Update Error : Model observation failed for time : 1

I use Bugpoint to check it , Bugpoint gives me the following information:

Checking to see if we can delete global inits: <cbe><crash>
What does this information mean?
(the ELF executable can be run correctly and even I link the generated
object files together one by one manually, the wrong is still there)
Is a bug in LLVM??
