I think that's an oversight, then. You shouldn't have to use the delayed edge

Dominique,
Have you been able to identify if there is an invalid optimization?
It seems using -ffast-math -ffinite-math-only is very error-prone. -ffast-math
implies -fassociative-math, which can generate NaNs

I have reproduced this failure, and the problem seems to be in GMP. You
mention that you set ABI to 64. I noticed that if I built GMP with the HP
