Comment(by altaic):

 Oh that makes sense. On x86-64, `RESERVED_C_STACK_BYTES` = 2048 *
 sizeof(SIZEOF_LONG) = 2048 * 8 = 16384 = 16k. Dividing 8192/16 = 512,
 which is roughly the number of iterations the program runs before
 crashing. Except they're not loop iterations, they are nested C calls
 which each get a whopping 16k of stack. So wouldn't this be expected
 behavior?
