What's more recent? the most recent "stable" release is 1.0.2! I can always
compile the latest dev release, 1.1.3, .. I'll try that, but I'm doubtful

Re: SegFault

Only difference is that the long error message has vanished, replaced by:

ERROR: general protection at 0x171ff: 73
ERROR: SIGSEGV, protected insn...exiting!

Same diff, Segfaults!

SegFault

[Dan Egli]

I thought everything was working grand, when all of a sudden, I noticed that
DosEMU was crashing when I ran a certain program. This program starts up,
looks fine for a while, then all of a sudden, DosEMU dies. The error is
listed below (I tried to extract it from the program header on the screen so
if something is missing, sorry)

ERROR: unexpected CPU exception 0x06 err=0x00000000 cr2=00000000 while in

Anyone know how I could fix this?

Re: SegFault

[Dan Egli]

Sorry! I was rushed  and I forgot some things!

I'm CCing the list on this..

Distribution: RedHat 7.3
DosEMU Ver (as reported by RPM) 1.1.1-3
DOS ver: Caldera Dr-Dos 7.03
Program: FastEcho 1.46 (I'd not be surprised if no one has heard of it).
EMS/XMS/DPMI define: 8192KB
CPU defined: 80586
PCI: On

Anything else that would be of value? I'll name it off if requested.

Re: SegFault

[Dan Egli]

One more thing that could be of value is the config.sys file, so it is
pasted below:

DEVICE=C:\DRDOS\SETVER.EXE
SHELL=C:\COMMAND.COM C:\ /E:512 /P
BREAK=ON
BUFFERS=30
LASTDRIVE=Z
HISTORY=ON,512,ON
COUNTRY=1,,C:\DRDOS\COUNTRY.SYS
DOS=HIGH,UMB
FILES=100
