So I've marked this as confirmed, since it seems that people are seeing it; however I'm confused.

On my lucid box (which dosemu wasn't previously installed upon) when I run dosemu it says:

------------
EXPERIMENTAL: using non-zero memory base address 0x110000.
You can use the better-tested zero based setup using
sysctl -w vm.mmap_min_addr=0
as root, or by changing the vm.mmap_min_addr setting in
/etc/sysctl.conf or a file in /etc/sysctl.d/ to 0.
------------

so I wonder why it doesn't do that for Bob?
(The dosemu I have is dosemu 1.4.0+svn.1999 in Lucid)

If the experimental thing does work it would be better; the mmap_min_addr is a security mechanism that aims to stop
kernel bugs being exploited for anything nasty, putting that down to 0 removes that protection.
