Unable to find dynamic linker breakpoint function.

Hi,

I know this question has been posted before, but I am posting this again
because I don't know how to fix this warning;

1. warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.

And then, how must I fix this problem;

2. The program being debugged stopped while in a function called from
GDB. When the function (std::string::at(unsigned) const) is done
executing, GDB will silently stop (instead of continuing to evaluate the
expression containing the function call).

My gdb run appears below.

Thanks,

Hareesh

PS: I'm running GDB 6.0. libstdc++ and glibc have been compiled with
DEBUG information.
