Not a guru, but...
There are two reasons I can think of causing this behavior. 
Either you have compiled with the optimizer turned on. This makes 
gcc rearrange code, omitting useless lines, and such. 
The other problem (hmm, I wouldn't consider optimizing a problem)
shows up when you run inlined code in C++, i.e. something like
=== foo.h ===
class foo{
 ...
 void bar( params ){ do_something;}
 ...
};
=== foo.c ===
...
foo Foo;
  Foo->bar(params);
...
=====
Somehow the debug formats mixes line number information and file
name, so you jump to funny places.
The cure for this is to use the stabs or stabs+ format. Go to SET's
homepage to find a 2.7.2 version that supprots stab, or 
(of this I am not sure !) use 2.8. I did the first thing, and those
problems are gone.
