GDB inserts some of its own internal breakpoints.  For example,
in the runtime linker/loader there is a special symbol GDB sets
a breakpoint on so it can be notified about shared libraries being
loaded or unloaded.  If you are using libthread_db on a target it
may install internal breakpoints to detect thread creation and
thread exit as well.
