From: Arthur Cohen <[email protected]>
Hi everyone,
We noticed inconsistent errors when running name-resolution 2.0 on
certain files, where an invalid error was triggered and the message was
from the `funny_ice` error finalizer function we had added as an easter
egg. We realized yesterday that the undefined value was actually our
`funny_error` boolean, which is supposed to be set only when resolving
specific easter eggs `AST::IdentifierExpr`s.
Since `funny_error` is a boolean, it does not get default-initialized in
the constructor of `Late` - which this patch corrects.
I will be pushing it to trunk directly, but this email specifically
concerns its port into 15.2.
Thanks a lot to Marc Poulhiès and Owen Avery for their help in
discovering and fixing this.
Best,
Arthur

funny_error field.
