I'm fairly sure that if a compiler stops working or has a bug, the expectation is that an engineer is capable of handling it in some way. I don't think any stakeholder will have much sympathy for "compiler stopped working, we can't do our jobs now" argument.

Is that wrong? My assembly programming sucks, but I can do it (slowly) if I need to. I'd expect most serious developers to have that level of knowledge.

For one thing, compilers actually work and enable you to do useful things.
