#23 Division by Zero at eip=0000b2d1

[Mario Duhanic]

Rhide (1.5,binary from rhide.com) seems to crash not
only when opening a file. This crash is reproduceable
(but not controllable). Rhide crashes also when using
its built in help and when compiling/running (djgpp).
There is always -- as it seems -- an errorlevel
(%ERRORLEVEL%) of 255. Without a crash it returns 0.
This bug also occured in its previous version.

This one had me foxed for AGES... But I finally spotted it!

If you attempt to open a file when the file is listed as
"Closed" in the WindowList, then opening the file will cause
RHIDE 1.5b to crash as described.

It doesn't matter how you open the file, you can click in
the ProjectWindow, select "Open" from the "File" menu, or
even press return on the "Closed" entry in the WindowList .
..the program will crash the same way under all conditions.

As stated, this is MOST annoying when using the InfoViewer
...the workaround is simple, but irritating. Before you
attempt to open a file or use the InfoViewer, goto the
WindowList (ALT-0) and delete any "Closed" entry for that
file ...all is well :)

A patch to fix this would be appreciated *A LOT* :)

OK, here is another victim :)

First of all, thanks Mario for your findings.
I saved up a full dump of the problem on my system...

It happened when I tried to compile a project, and the compiler found a bug in an *auxiliary* file. Yes, this auxiliary file was not opened, only the main file was (to keep a decent overview).
