[LLVMdev] Debug information causing assertion

[Villmow, Micah]

We have a test case where we are hitting an assertion in the X86 code generator. The assertion is: "Assertion failed: TheCU && "Unable to find compile unit!", file .\..\..\..\lib\CodeGen\AsmPrinter\DwarfDebug.cpp, line 1411"

The bitcode is attached.

What I am trying to figure out is what is malformed about our debug that is causing this error? This is reproducible with 'llc -march=x86 bugpoint-reduced-simplified.bc'.

As far as I can tell, the variable 'TheCU' should map to the metadata node !24.

Is this a bug?

Thanks,
Micah
