minivmac v0.37 Sytem Error when booting some emulated machines

Hi!

I built a tinyMac for this year's MARCHintosh. So far so good, I compiled minivmac and it works with a System 7.1 install that I have been using on many real or emulated machines for over 10 years. Usually I emulate a Mac Classic (because I have a real one too) or Mac II if I want color.

Then I wanted to bring the emulated system online. First step was to compile minivmac's 0.37 beta with LToUDP support. But here comes the problem. Booting the same image that was fine with 0.36 results in a System Error Bomb (Error 4, division by zero) This is true for Mac Classic and Mac II emulation. When I start minivmac as a Mac Plus it does however run normally (LToUDP seems to work too).

Any Ideas? Is this a known issue?
