Thank you, Franta, for getting back to this problem. In the meantime I
ran strace and googled the issue and saw some bug reports on this
segmentation fault. Here is the last part of the strace listing. (Btw.,
I'll try your rpm tomorrow, it is getting late here, and I have to clean
up my system again before I install your rpm, and will let you know if
it worked).

There is also an error just before the raw socket message about not
finding libc.mo file for messages in locale, but I don't think it is
important. Interestingly, there is such a file in my /user/share/locale/
directories in many languages, including en_GB, but not in plain en.
I think the problem is with the mmap, mprotect stuff.
I hope this helps the developers.

Hi Janos, this reminded me of something similar that I have met cca
three years ago. You can try to find my thread "same distro, svn1999
DOSEMU crashes on some PCs on SEGV, on others run fine" from
12/13/2010 in dosemu-users list - this was on Fedora 14, but this may
be same problem which you see now on Fedora 3. But something better -
I managed to compile almost last dosemu devel version on Fedora 3
i686, and this work well at me machine, both in console and under X
(also both in terminal mode 'dosemu -t' and with native X (xdosemu).
Because there was lots things corrected and improved, maybe it will
run on Your system too. There is only one particularity: after
installing RPM and first dosemu run must be copied kernel.sys to C:\
drive: cp /usr/share/dosemu/drive_z/kernel.sys ~/.dosemu/drives/c/ You
can download RPM and SRPM package at:
http://www.hanzlici.cz/packages/fedora/dosemu/fc3/dosemu-1.4.0.8-git621.g431face.3.dbgemu.fc3.i686.rpm
http://www.hanzlici.cz/packages/fedora/dosemu/fc3/dosemu-1.4.0.8-git621.g431face.3.dbgemu.fc3.src.rpm
Good luck, Franta Hanzlik
