Nope - it lists the "correct" line numbers from the wrong file.  I'm 
guessing this is a problem in the binutils addr2line, is that what it's for?

It says "super.c", then gives the corrent function declaration.

I get - Error: invalid command name "gdbtk_loc"

Yeah I realise that - this is a cross-debugger for an embedded system, 
short of forward-porting it myself (*not* gonna happen!) I don't really 
have a lot of options.

I'm not too stressed about this, I can just rename the source file and 
rebuild the project as I need to, just wanted to know if there was 
something simple I might do.

Thanks,

John
