Thanks! I've taken the liberty of filing this at https://sourceforge.net/p/wxhaskell/bugs/84/
Conal, am just CC'ing you because you've been suffering most from this GHCi bug, which I think sounds important. Just letting you know that we now have a BTS ticket for it, and some technical info on said ticket. Sorry for not being more helpful; just hoping this tiny bit of admin dot-connecting can help move things forward. As I understand it, the new new wxHaskell crew have been very active — thanks guys! — but are now focused on getting a new release out from all their hard work lately. So this GHCi-related stuff would have to be after said release On 8 October 2013 16:16, Jeremy O'Donoghue <jeremy.odonog...@gmail.com> wrote: > > When I last looked at the problem, the issue was that wxWidgets libraries > use static constructors and destructors in some places. > > Problem with static constructors is that they typically run before main() - > or its equivalent - is called.
