[Julien Lerouge]

I'm seeing the following when doing a universal debug build of llvm-gcc (non
bootstrap) for Darwin, when configuring libiberty for the i686->powerpc part:

Assertion failed: (I != CompileUnitMap.end() && "Missing compile unit."), function FindCompileUnit, file /Volumes/llvm
/src/head/llvm-src/lib/CodeGen/AsmPrinter/DwarfDebug.cpp, line 922.
conftest.c:53: internal compiler error: Abort trap
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://developer.apple.com/bugreporter> for instructions.

Any chance it's related ?

Thanks,
Julien
