Everything about this bug looks like better compiler optimization hitting code with a latent bug, and as expected using either gcc-9 or -O2 "fixes" the problem. -fsanitize=undefined finds: util.h:11:26: runtime error: shift exponent -8 is negative util.h:11:44: runtime error: shift exponent -8 is negative The buggy code is: https://salsa.debian.org/pkg-security-team/aeskeyfind/-/blob/debian/master/aes.h#L14-15 https://salsa.debian.org/pkg-security-team/aeskeyfind/-/blob/debian/master/util.h#L11 > Best regards, > Jan >... cu Adrian
