I've seen similar issues when using icpc (14.0.2) even for trivial standalone tiny_ad examples. It seems to be caused by over optimization:
tiny_ad
-O3
-fp-model precise
-O2
tiny_ad_re runs fine with Intel C++ version 19

examples. It seems to be caused by over optimization:-O3
gives wrong results unless-fp-model precise
is also set.-O2
gives correct results.
