--- Comment #20 from Rich Felker <bugdal at aerifal dot cx> ---
Is the actual bug here fixed yet or planned to be fixed? Speculation about
better optimizations around otherwise-pure/const functions and errno is nice I
guess, but the root issue here is an existing wrong-optimization that breaks
real code (and that would still be formally incorrect even if it didn't).

We can worry about improving situations that can be improved (if there are any)
after fixing the actual bug.
