State-Changed-Why:
    You did not provide a testcase as mentioned in
    http://gcc.gnu.org/bugs.html
    
    Also, gcc 2.96 is not a version supported by the GCC project.
    You should report bugs about this version of gcc
    to Red Hat: http://bugzilla.redhat.com/bugzilla
    
    Do you have a reproduceable test case?

    if(b > a)
    b++;
    if(b > 5)
    a=3;
    
    
    
    Cannot reproduce problem with above testcase using
    gcc 3.0.4.  Consult Red Hat for further issues regarding
    gcc 2.96.

>Organization:
>Environment:
RedHat 7.0 with GDB 5.1.1
>Description:
Using included files for function, GCC seems to generate incorrect file information for the addresses coming from the included file. GDB doesn't seem to be at fault as a cross-compiled GCC/GDB (ARM ELF32/DWARF) seems to work fine.

The problem is either at GCC generated debug information or GDB reading the debug information.
>How-To-Repeat:
Unzip and compile:
gcc -g -o test test.cpp

Debug using GDB, break at main, and step a couple of lines. This is the output from GDB:
