Subject: Re: be able to break inheritance of LD_LIBRARY_PATH

Instead of patching the dynamic loader, you can supply an LD_PRELOAD module
that would remove/modify LD_LIBRARY_PATH appropriately at startup:

#include <stdlib.h>

void __attribute__((constructor))
remove_ld_l_p(void)
{
  unsetenv("LD_LIBRARY_PATH");
  unsetenv("LD_PRELOAD");
}


HTH.
