That's a rather new GCC and rather old GDB.

What kind of problems?
Did you compile with -O, -O2, or -O3?
Debugging optimized code is always problematic: the compiler may not
have assigned address for a local variable at all.

Start by compiling with '-g -O0'.
If that doesn't work, try current GDB built from CVS Head.
If that still doesn't work, show us your compile line, and output from
'gcc --version'.
