RE: [cdt-dev] MBS Slash issues

[Doug Schaefer <DSchaefer@xxxxxxx>]

The symptom I'm seeing when debugging gdb is that there are two entries in
the symbol table ../main.cpp and ..\\main.cpp and only one of them has the
line number information. Unfortunately, gdb is picking the wrong one and
giving up.

I am going to raise a bug with the MinGW folk and see if they can help me.
I'm not sure whether it's the generation of the symbol table by gcc or the
reading in by gdb/bfd.
