Delta with level 0 topformflat completed after 18h36min, reduced testcase
attached. Failure is now independent of argv[0] length and always just
segfaults (at -O1 -funit-at-a-time, not -O1). I've started a level 1 reduction
now, but I assume this will take a long time. I have manually reduced main() to
reduce compile time, but there was not much to remove - removing more will
either magically fix the testcase or break it compile-wise.
