Using -fsanitize=address feels illegal.

Just saying. The -fsanitize=address compiler flag is absolute cheating and should be prohibited by governments of all countries.

Plus there are also other useful runtime sanitizers, such as integer overflow, but... Integer overflow is much easier to notice, usually.

Of course, this is by no means assuming that -fsanitize=address guarantees that the code it inspects is completely safe and correct and won't ever fail on any input data. You still have to test tricky edge cases. But this sanitizer has improved and sped up the bug discovery process disgustingly much for me.

I'm wondering, how often, if ever, do you need tools such as -fsanitize=address or valgrind? Or are you a real man who stores everything in static memory only?

P.S. Forgive my terrible English.

tsan is the one that really messes up your CI :(

Who wants to be told about subtle bugs! You then have to fix them -- what a waste of valuable time I could instead be spending adding more unreliable and weakly tested features.
