Hi,

the attached reproduction script causes a clang assertion here:

clang:
/sapmnt/trextest/trex_test/mrich/llvm34_trunk/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp:1356:
void llvm::CompileUnit::createGlobalVariableDIE(const llvm::MDNode *):
Assertion `VariableDIE && "Static member decl has no context?"' failed.

This works on clang 3.3, so it is a regression on trunk.

Best regards,
