What I do is to add a dummy routine after the call to dlopen (in
src/modules.cc):

void my_dummy_breakpoint()
{
}

       handle = dlopen (library_name, RTLD_LAZY);
       my_dummy_breakpoint();

(if I'm lazy, I use atan(0) for the dummy call). Then, the gdb
invocation becomes:

  gdb gpsim
  gdb> b main
  gdb> run
  Break at main ...
  gdb> b atan
  gdb> c
  Break at atan
  gdb> break at whatever_i_want_to_debug
  gdb> c

But, as usual, there is more than one way to skin a cat.

If the only tool you've got is an axe, every problem looks like fun!
