Try it with gdb -nw and see what happens.  But I bet it is gdb (or gcc) 
because the GUI rely on it (them) for the symbolic information.

See my comments below.

          ^^^^^^^^^^
gdb thinks you've stopped in the middle of a source line.

Which version of gdb are you using?  Also, have you compiled your
program
with optimization?  

Things to try, in order:

Compile without optimization.
A recent version of gdb.
A different version of gcc (the compiler creates the line number info).
