Hello,
I'm trying to run the NewViews 1.41b accounting program, which has been
happily working in dosemu / DR DOS v6.0 for years. Now it gives an Illegal
Op error and exits when trying to open the accounts books directory.
The machine is running ubuntu/x86_64, and NewViews works correctly up to
package version dosemu_1.4.0+svn.1999-1 but the next package release
does not work (dosemu_1.4.0.7+20130105+b028d3f-1).
The following excerpt from the boot.log was with the latest git tree from the
'devel' branch. The Illegal Op is always the same, although the CPU exception
code seems to vary depending on the release of dosemu. Various parts of the
application can be navigated through, but as soon as the directory containing
the accounting books is selected the crash occurs. I presume it is scanning
the directory and opening files.
I tried various cpu emulation options. I also found one similar crash report in
the bug system that mentioned setting vm.mmap_min_addr to 0. Neither
option helped.
Excerpt from boot.log follows.
The full Debug +a log is at http://www.bork.org/~mort/boot.log
Please let me know if any other info might help.
Thanks,
mh

Hi Martin,
I think you'll need to report this over at http://sourceforge.net/p/dosemu/bugs/ as this list is very quiet these days, especially for development.
Hope it helps,
Andrew
I thought I heard that you cannot run 16 bit DOS programs on a 64 bit
box. And I thought that applies to wither Windows or Linux.
Let me know as I have a 64 bit box that I am not using because of this
DOS issue.
John
