DOS Frotz crashes on real hardware

I posted to a few places asking for people to test DOS Frotz on real hardware. So far, only one person replied. The test machine was a 486DX4 running at 75 Mhz with 24M of RAM and no sound card. It crashes horrible after three but less than ten moves. Test game is LostPig.z8. The computer's display was photographed and sent to me. I'm just going to release 2.44 now. This is the transcription:

>go west
Grunk no allowed in field. That probably OK, because Grunk no think pig tall
enought to climb over wall.

>look around
Grunk not see that there.

>find the goddam pig
Grunk no know where that at.

>lol
Grunk not know what that mean.

>go east
Forest look dark. Pig probably some place in there, but Grunk not know which way
to go. Not want end up lost in forest with no pig.

>go west
