FIXME: The following RUN line should fail, regardless of whether debug info is
|
|
enabled or not. Normally this would result in an error due to missing _PchSym_
|
|
references, but SymbolTable.cpp suppresses such errors. MSVC seems to have a
|
|
special case for those symbols and it emits the LNK2011 error.
