--- Comment #5 from jeremy rutman <jeremy.rutman at gmail dot com> --- Using gcc 14.0.1 20240117 (experimental) [master r14-8187-gb00be6f1576] I was able to compile when not using any flags: $ /usr/lib/gcc-snapshot/bin/cc -c aesDecrypt.c -o aesDecrypt.o But when using the flags as before $ /usr/lib/gcc-snapshot/bin/cc -Wall -O3 -DNDEBUG -fomit-frame-pointer -c aesDecrypt.c -o aesDecrypt.o the compile kept going for at least one hour on my machine before I aborted.
