Assefa, did you have time to look at this one already? It can be fixed on our
support contract, but please do let me know before if it will be more than 1 or
2 hours.

 Do you see any thing wrong in my tests ? Not sure where to go from here.

Assefa, I just rechecked all this. Using mapserver 4.6.0 Windows binary
(14-06-2005) I do still get a crash. But using CVS version (4.7) everything goes
well.

When you tested with 4.6, did you test with the current 4.6 branch in CVS, or
with the actual 4.6.0 release binary?

Apparently this has already been fixed in the meantime ....
For a while I was thinking I must be getting crazy since all the testcases I
provide work for you :-) but I could reproduce with the 4.6.0 Windows release
binary.

Thanks. I'll close this bug.
