Araq, my recent idea was to replace above code with
proc `procName`(self: `wt`; p: proc (self: `wt`, arg: `at`); a: `at`) =
when compiles(GC_ref(a)):
GC_ref(a)
`scName`(self, `procNameCdecl`, cast[pointer](a))
else:
var ar: ref `at`
new(ar)
deepCopy(ar[], a)
`scName`(self, `procNameCdecl`, cast[pointer](ar))
`procName`(`widget`, `p`, `arg`)
For this example the GC_ref() part is executed and GC_ref() crash. May it crash
because a is a string literal and not a var? I hope at least the deepCopy part
is OK.
