So you are still saying that I added the options for fun?
(Thank you, as said it did take significantly more than
an hour to find them.)

The op used an equivalent for both small and hardened in
his configure line that imo is not supported by us, I found
a supported configure line that has the same effect on
config.mak and the resulting binary.

I knew that you were able to solve the riddle without
the configure line but I still believe it makes sense
for you to also being able to test a fix.

I do not understand why you wrote you cannot reproduce
when you did not even try to.
Since the issue is not easily reproducible with clang, I
still wonder if it is reproducible on Windows.
