I know of some problems in this area, but it's not clear which one is
your problem here.  Could you try building gdb with
--enable-profiling?  It should generate a gmon.out.  That might not
show the real problem; if you want to just build a debuggable version
and use oprofile, that might work better.  It depends whether GDB is
eating CPU or being wasteful with ptrace operations.
