This is absolutely correct, and the article worries me for that reason. C programmers shouldn't learn "Heisenbug == compiler error" -- that's rarely the case.

This is absolutely correct, and the article worries me for that reason. C programmers shouldn't learn "Heisenbug == compiler error" -- that's rarely the case. Compilers aren't generally formally verified, but they're also very heavily tested, and it will rarely happen that you expose a compiler bug. It's far more likely you're relying on UB in some way.

The author states that this has only happened 3-4 times in 30 years. I don't see anything that would make a reasonable programmer suspect that this is always the case or even usually the case.
