Dosemu 1.4.0.1 causing "general protection" error on Ubuntu 10.10

[Brain]

Binary package hint: dosemu

I have been using dosemu on Kubuntu 9.10 with Borland compiler (TLINK) for a long time without problems but after upgrading to version 10.10 I cannot run TLINK any more and I'm getting error:

ERROR: general protection at 0x301ff: 0

This seems to be related to the dosemu 1.4.0.1 package (actually 1.4.0+svn.1999-2) in Ubuntu 10.10, since the old version of dosemu (1.4.0.0) run from a backup of the 9.10 system is also working on 10.10.

I couldn't find any hints on the Internet or anyone having the same problem. Can anyone please help me?

The only strange thing I noticed as a difference between the two versions of dosemu is the extra line "CONF: not enough privilege to define config variable c_user" on the non-working 1.4.0.1. But I have no idea what it means.

The boot.log output from dosemu 1.4.0.1 is attached.

Well, then this version of dosemu should be IMHO removed from the
official distro and replaced with a working one ;-)

As a workaround I've copied over the 1.4.0.0 from my 9.10 backup and
everything is fine. But poor people who have no previous backup...

I don't understand that Debian provides version of dosemu_1.4.0+svn.1999-2_i386.deb in stable packages.
So many people have found a bug with the programs written in PASCAL

I have tried this version on dosemu with different dconfigarations of ubuntu and it never works in Turbo Pascal

Can you tell me where does the bug come and in any case dosemu_1.4.0+svn.1999-2_i386.deb is not stable dosemu

Sincerely
Patrice Lemonnier

Programs developed for the real mode in turbo pascal work correctly.

But programs developed in 16-bit protected (DPMI) don't work.

Status changed to 'Confirmed' because the bug affects multiple users.

[lemonnier (p-lemonnier1)]

I have no problem with the version 1.4.0 svn 2010-1

I have download this paquet to debian in the experimental version
And now for the moment i don't observe bugs.

Best regard

For me lemonnier's solution works also.

[Paul Castle (castlesoflaxey)]

This also affects me. Under LUbuntu 10.4 DOS program Advanced Revelation works 100%, and never crashes.
Under 11:10 it crashes almost as soon as I do anything.

I will see if I can install the 10.4 version in 11:10 as a workaround when I get some time (thanks for the hint)
