Just FYI, I found that the offending assembler line is:

.def __vptr$__basic_file<char>; .val 0; .scl 8; .type 01124; .endef

(I compressed some excess whitespace there).

My assembler knowledge is pretty shallow, so that line is Greek to me.
Just trying to provide all the information I can...

Looks like it's indeed confused about header locations, but should be
easy to fix(?)...
