You can start dosdebug *after* dosemu
is locked up, not before (not with -H1).

You can use the memory debugger njamd.
It can work with dosemu, but only if
you change every instance of sigaction()
call to dosemu_sigaction() call in emu.h
and recompile the dosemu.
Then you can set LD_PRELOAD to libnjamd.so,
run dosemu, and if it segfaults, then
there is probably a memory corruption
and you'll need to create a stack trace
with gdb at that point.
If this is the case, please open a bug
report on BTS for it.
