Comment(by dterei):
Was doing some work in recompilation avoidance for the SafeHaskell work
and came over this bug. I was thinking, the easiest way to fix this would
be to store a new fingerprint in the interface file for a module that is a
hash of the flags that if changed should trigger recompilation. So '-main-
is', probably '-O' should be part of the hash but '-Wall' shouldn't for
example. If this sounds like a reasonable plan then I would be happy to
code it up since it would be useful somewhat to the SafeHaskell work.
Recompilation of a module on this condition I don't think should trigger
recompilation of modules depending on it though.
