(and on which side of the vma > it is) To Arnd: Another thing you should probably do is to build dosemu with debug information, and then look into ~/.dosemu/boot.log after it crashes. That will give you the contents of /proc/self/maps, a gdb backtrace and various other goodies. I've checked it myself but can't reproduce, neither with plain dosemu 1.2.2 nor with current CVS.
