[LLVMdev] An error when insert a function call in the IR

[Eric Lu]

I insert an function call in the IR, and causes the following error. and
the error seems to happen on some cases. The attached file nest.c can be
 processes successfully and the nest-ddp.ll is the output file, but the
nr__routines.c will fail.

llvm-3.2-svn/lib/VMCore/DebugLoc.cpp:60: void
llvm::DebugLoc::getScopeAndInlinedAt(llvm::MDNode*&, llvm::MDNode*&, const
llvm::LLVMContext&) const: Assertion `unsigned(ScopeIdx) <=
Ctx.pImpl->ScopeRecords.size() && "Invalid ScopeIdx!"' failed.
