Although probably I'm not able solve this problem, I can recommend
to You to trying run Your program with different '$_cpu_emu' values
and with different dosemu modes, as e.g. starting DOSEMU from xterm
with '-X' (X-window mode), '-t' (terminal mode), and '-S' (SDL mode
- when You have support for it compiled in). I have accounting SW
which run in X-window mode, but crashes DOSEMU in terminal mode.
It seems as debugging DOSEMU crashes isn't too easy, I would like
when someone with DOSEMU internals skills could give me advice how
start solve this problem.

And, when You wan and there are some simple steps how evoke Your
DOSEMU crash, I can try run it on my configuration, when You pose it
somewhere.
