A change has been committed which seems to fix this.
The fix depends on the fact that the buffer passed to xDosSetPathInfo has been allocated on the stack and that the stack has not grown by nearly 64K since then.

Running the debugger I found that the buffer being passed to xDosSetPathInfo crossed a 64K boundary (0x000bfff4).
After reading the comments preceding the function, figured that the traps were due to this fact. Changing the code to ALWAYS copy the buffer to a local (stack) buffer stopped the traps.
