If your system gcc mis-compiles something, you most probably can reproduce it systematically. You can try building everything with -O2, and then the few files you suspect are broken with -O0 or with a different version of gcc. Try adding -Wall -Wextra to CFLAGS when building those files, and you may find that we may be doing something that is undefined (C wise), and gcc is taking advantage of that when optimizing.
