When I try to convert https://github.com/ZirconiumX/sunfish/blob/master/sunfish.py to C++ the Shed Skin compiler crashes.

Arch Linux 64 bit using Shed Skin 0.9.4

Matthew:out

thanks for reporting and the interesting program. I'm tempted to try and add this to the shedskin example set.

this problem has been fixed in git shortly after releasing 0.9.4. unfortunately there are not enough other improvements since to do a 0.9.5 release.

the problem occurs typically for programs containing actual dynamic types, so it may be a bit more work to get it work. also I see the program seems to be a heavy tuple user (for moves), which doesn't translate very well to fast C++ code.
