nightly build 3/13/2000.
I whittled the URL file down to the following, and still it crashed:
<HTML>
<HEAD>
</HEAD>
<BODY>
<B><FONT FACE="Arial" SIZE=5><P>a</P>
</FONT><FONT FACE="Courier" SIZE=4><P>w</P>
</B>
</FONT><B><FONT FACE="Arial" SIZE=5><P>a</P>
</FONT><FONT FACE="Courier" SIZE=4><P>w</P>
</B>
</FONT> <B> <A><B><FONT FACE="Courier" SIZE=4><P>w</P>
</B>
</FONT><B><B><FONT FACE="Courier" SIZE=4><P>w</P>
</B></FONT><B><FONT FACE="Courier" SIZE=4><P>w</P>
</B>
</FONT><B><FONT FACE="Courier" SIZE=4><P>a</P>
</FONT><B><FONT FACE="Arial" SIZE=5><P>a</P>
</FONT><FONT FACE="Courier" SIZE=4><P>w</P>
</B>
</FONT><B><FONT FACE="Courier" SIZE=4><P>w</P>
</B>
<B><FONT FACE="Courier" SIZE=4><P>w</P>
</B>
</FONT>
<B>
<FONT FACE="Courier" SIZE=4><P>w</P>
</B>
</FONT><B><FONT FACE="Courier" SIZE=4><P>w</P>
</B>
</BODY>
</HTML>
It seems the crash is being caused by not having an equal number of <FONT> tags
as </FONT> tags. I tried to whittle more off, but this is the minimum crash causer.

Crash confirmed for page at URL, using 2000-03-13-17-M15-nb1b on WinNT.
Dr. Watson reports access violation; log to follow.

I cannot reproduce this in NT. Petersen, do you see this one?

I don't get a crash when opening this attached testcase in the March 23 Mac
build. I will check under Win 98 and NT.

Opening the reduced testcase attachment in the same Mozilla window only causes
the crash sometimes (and even then, after 1 or more reloads). However, opening
the testcase link in a "New Window" causes the crash 100% of the time.

Using the attached test case and url, I have successfully loaded the files in a
new and current window without a crash. Tested under Win NT, Win 98, and Mac 9
with April 12th build.
Ah -- ok, it crashes for me now. But it looks like a stack overflow in layout.
Off to buster.

tested on winNT, debug and opt builds, on 2 different machines
also tested on linux debug build
no crashes.
I think the recent data structure size reduction in several key block/inline
classes may have kept us within the allocated stack space.
Should be verified against mac, which has the smallest stack of the 3 platforms.
