Hello Bernhard,
I only tested with Rebel Decade, but it may be the same problem.
Current SVN has a fix, or you can change
in src/dosext/dpmi/dpmi.c:
@@ -3412,6 +3412,7 @@
but that method is unreliable for 32-bit DOSEMU on x86-64 kernels.

if (_esp > 0xffff && !Segments[_cs >> 3].is_32 && Segments[_ss >> 3].is_32 &&
+ Segments[_ss >> 3].type != MODIFY_LDT_CONTENTS_STACK &&
_esp > GetSegmentLimit(_ss)) {
D_printf("DPMI: ESP bug, esp=%#x, ebp=%#x, limit=%#lx\n",
_esp, _ebp, GetSegmentLimit(_ss));
Let me know if it works for you.
Bart
