The __FILE_FULL_PATH__ macro is a feature that I added to the DMD compiler in
the commit you referenced (67d08406f7451954cd8caf5faea6a2a87244f8e7).  I never
tested using it as a default argument to a function parameter so it looks like
you've found a bug.  You are welcome to fix this.  If you decide to fix it, I
would also add a unit test. The original unit test I added for this feature is
in <dmd>/test/compilable/line.d, it may or may not be the correct place for the
new unit test, but it should definitely be added somewhere.  Maybe a test like
this:

void testFileFullPathAsDefaultArgument(string preBakedFileFullPath, string
fileFullPath = __FILE_FULL_PATH__)
{
    assert(preBakedFileFullPath == fileFullPath);
}

testFileFullPathAsDefaultArgument(__FILE_FULL_PATH__);

Let me know if you have any questions.

P.S. Just out of curiosity, what were you using this macro for?  I spent alot
of time convincing the D maintainers that it was a useful feature so I'm
curious what uses people have found for it.
