According to https://github.com/primalib/prima/actions/workflows/profile_integer_kind.yml, PRIMA_INTEGER_KIND slightly affects the result of the following solvers when compiled with -Ofast -fno-stack-arrays.

  • PRIMA_INTEGER_KIND = 16: uobyqa, newuoa, bobyqa, cobyla

  • PRIMA_INTEGER_KIND = 64: cobyla

No visible difference is observed when compiled with -ffast-math.

This is strange.
