wxc segfault in wxHaskell

Vote count:

I was trying to test wxHaskell. Since I tried to compile wxHaskell against wxWidgets 3.0 on Windows/MinGW32 unsuccessfully, I reverted back to wxWidgets 2.9.5, and was able to install wxHaskll by cabal install wx.

When I tested the Counter example in reactive-banana, I got a segfault. Doing a gdb on Counter.exe shows the following call stack. I was wondering if anyone has encountered a similar error, or had any solution?

Program received signal SIGSEGV, Segmentation fault.
