The bug also exists when running PHP on Linux. And it may be reproduced with Mozilla, too. Please
don't forget this one before 4.0.7 is released.

Reproduced with IE 5.5. The rfc1867.c has some bugs
in it after all..

Marked as fix before release. (4.0.7)

Crashes with 1.3.14, 1.3.17 and 1.3.20.

I've tried it with IE5, IE5.5, Mozilla 0.9.3 and Netscape 6.1.

Whoa, just found it _doesn't_ crash with Netscape 4.08 or Opera 5.11.

I can't test it in Linux, as I'm currently sans-external-DSL-modem and therefore stuck in
windows until a new one arrives.

Just one more thing: What version of Apache? 
And does this happen with any browser? IE / NS / Mozilla ?

I can not reproduce it with your form and with latest CVS.
Please provide a GDB backtrace of the crash (using latest CVS of PHP)
