I am still using an old 16-bit drawing package called "DrawingBoard" from
Ashlar.  I have been running this under Oracle's VirtualBox until last year,
when VirtualBox upgraded to version 6 and DrawingBoard became very slow (more
than 10 minutes to open a VLM drawing file which would normally take a few
seconds.  Than I tried DrawingBoard under wine and it actually works
flawlessly, it opens any VLM file quickly and everything seems to work. 
However there is 1 particular VLM file where wine crashes at the end of reading
the VLM file.  See attached backtrack.txt.  I copied this file from backups to
make sure the file is not corrupt, but still a crash.

Than I run DrawingBoard again under VirtualBox and the same VLM file did open
(but slowly), I made a small change and saved this new drawing under a
different name.  I tried wine again on this new file, but again wine crashed.
