Any news or prospects on this problem?  I've switched to gtk2hs because of it, but I'd like to switch back before I get much more invested in gtk2hs.  I'm working on new, GPU-based versions Pan [1], Vertigo [2], and Eros [3].

Summary: process crashes on second 'start'

Initial Comment:
Running two 'start'ed actions kills the process under ghc and ghci.  Example:

 import Graphics.UI.WX
 main = io >> io where io = start (frame [] >> return ())

OS: Windows XP
Software versions:
 ghc:        6.6
 wxWidgets:  2.6.3
 wxHaskell:  0.10.1

The demonstrator lives in and does not need GHCi
at all.
I get a segmentation fault under Linux.

Can anybody explain what is going on?

Conal, just to mention that I'm sending a demonstrator for this bug (see
wxhaskell-devel).  Not sure what we should do about it, though.
