Would be nice to know if this is working with gdc or ldc. In theory it
should work as we use gcc's exception handling/stack unwinding so it's
probably a dmd bug.

Slightly off topic, but maybe interesting:
Things can get really nasty if the GCC backend somehow decided
a function is nothrow and you throw from there. Unless GTK uses some
special __nothrow__ attributes that shouldn't happen in C, but I've seen
D code that throws from @nothrow functions and at least on ARM that
crashes... Might be a gdc bug or a problem with the D language
specification.
