I was using the debug build (vc7, metrowerks, gcc). If you take a look 
at the above, it says ("unknown software exception"), so the just in 
time debugger isn't being invoked and the gcc stackdump was empty. I do 
not know a way around this and do not know why the 
generator.jam/type.jam changes are producing it.

I want to attempt to locate the underlying problem, but do not currently 
have the time to work on it. The only way I see of finding the problem 
is injection of trace code into the bjam source then running bjam with 
the good version and bad version of generator.jam/type.jam, comparing 
the result.

I have had a few exceptions in bjam that I haven't been able to 
reproduce (i.e. they resolve on the next invokation of bjam). Because of 
this, I am switching to a debug build and will report what I find.
