Hello,after migrating to stretch an old business program crashed, as this isessential here I tried various things which might be useful inanalyzing the DPMI behavior.some workarounds:current solution here: everything is running fine on stretch with thejessie dosemu package without any tweaks!dosemu2 also was able to run fine but there was no way back to dosemu1.4, I couldn't sort out why, so as I was short in time I reinstalledthe whole systemthe stetch dosemu package runs with$_dpmi = (0x0000)in dosemu.conf which is a strange settingon the 386 architecture does not come up with the stack overflow, itwas possible to run the software but I prefer amd64 on the machine, sothis was just a short test.the relevant part of the bootlog:======================= ENTER CPU-EMU ===============ERROR: PM stack overflowed: in_dpmi_pm_stack=452leavedos(enter_lpms|1283) called - shutting downleavedos() called from within a signal context!======================= LEAVE CPU-EMU ===============hope this is related/eric
