[LLVMdev] stack dump

[Alex]

Hello,

I am also getting very frequent this Stack dump error. 
I am using the most
recent version. And it appears related to passes 
written from opt tool.

Basically, this kind of error:

0  opt          0x08eaf9a8
1  opt          0x08eaff24
2               0xb774a400 __kernel_sigreturn + 0
3  patternDC.so 0xb7744c48
....
run(llvm::Module&) + 38
10 opt          0x081a290f main + 6095
11 libc.so.6    0xb74574d3 __libc_start_main + 243
12 opt          0x081b8509
Stack dump:
...
and then 
Segmentation fault      (core dumped)
