--- Comment #1 from Ondrej Bilka <neleai at seznam dot cz> ---
There is already a functionality to support this. You need to interpose a
_mcleanup by compiling shared library containing function like one below and
then LD_PRELOAD it for your program.

void _mcleanup (void)
{
  if (user condition)
    {
      void (*p)() = dlsym (RTLD_NEXT, "_mcleanup");
      p ();                                        
    }      
}
