Because I haven't here the original post, I answer to Eli's answer.
The problem with GDB and C++ is realy a hard problem. It is not common
problem of GDB with handling C++ (GDB can handle C++ very good) but it
is the problem with the debugging information. The format, which is used
by DJGPP (SDB debug information) is not checked correctly by GDB or
there
is not all information, needed for debugging C++ programs.
I have tried many, many tricks to get GDB work correct for C++ but
nothing
had the expected result.
You can see the problem, when you look in the sources for GDB how it
reads
COFF files with SDB debug information. There is nowhere any code for
detecting the language from the source file and there is also nowhere
any
code for handling C++ specific stuff. I have tried to modify it but this
is
very hard and I gave up. Now I'm using stabs debugging information (with
my
own patched gcc) and I must say, GDB is very powerfull in handling C++
programs.
