With the following attachment ("Hello2.ll"), compile using the following

   llc -O0 -disable-fp-elim -filetype=obj Hello2.ll
   /usr/bin/c++ -g -o Hello2 Hello2.o 

Now run dwarfdump -ka on the resulting executable:

   dwarfdump -ka Hello2

Drawdump prints out a bunch of messages of the following form:

*** DWARF CHECK: DW_AT_decl_file: does not point to valid file info ***

Note that this issue occurs using both the old DIFactory and the new DIBuilder.
