32 Bit:

Second Test Program (derived from a crashing conftest)

#include <ctype.h>

int
main ()
{
  int j = 0;

  j = islower(0);

  printf("j is: %d\n", j);

  return 0;
}

        ld4 r14 = [r14] <<<--- crashes here. Missing addp4 r14 = 0,r14

If you insert the addp4 r14 = 0,r14 before that command (like gcc 4.9.3 does),
the program compiles and runs correctly

I'll upload the .s for "IsLower.c" - it's definitely a 32 bit executable, so
the correct options are being passed around.
