marking all.  it crashes on windows as well.

Whiteboard: [TESTCASE]
I have tracked down the frame that causes this. Turns out it's completly empty
of any content. Here is a simplified testcase:

<HTML>
<HEAD><TITLE></TITLE></HEAD>
<BODY></BODY>
</HTML>

I think the empty TITLE is causing the crash (invalid page fault in
module XPCOM.DLL), leading to nsString::CompressWhitespace on an empty string.
I think this could be a serious problem so I am going to be bold enough to
raise severity and reassign to XPCOM.
BTW, I tested using apprunner 1999-09-10-10-M11 on Windows 98.

Rick this is either string or layout. Either way, your I think. Let me know if
not.
Status: NEW → ASSIGNED
This is non-reproducable on NT or mac. I'll try my linux box this evening.
It doesn't crash apprunner 1999-09-17-13-M11 on Windows 98 either.

Summary: http://www.topica.com causes a crash → http://www.topica.com loads, but doesn't display
it doesn't crash for me on linux any more.

but it does fail to display.

when I go to http://www.topica.com, it appears to load the page, but fails to
render it.   (it comes up blank)

changing url back to http://www.topica.com

Eric -- this looks like a frame bug to me. The content model is very wrong here.
Assignee: pollmann → harishd
Component: XPCOM → HTMLFrames
Hmm, the content model being formed incorrectly is exactly why I'd say the bug
was in parser/content sink area - if we don't get frameset/frames content, we
can't get corresponding frames.

From dumping the content model of this document in viewer, it looks like a body
tag is being opened when a frameset should be opened instead.

I got this bug to go away by removing the very first line of the file.  The
first line is:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
"http://www.w3.org/TR/REC-html40/loose.dtd">

I tried replacing this with the strict and frameset DTD lines, but the result
was also no rendering.

Harish, can you take a look at this bug and figure out why not frame/frameset
content is created?  I'm attaching the original, then my 'fixed' test case.
Status: NEW → ASSIGNED
Target Milestone: M11
My bad ( very bad..uuucckkk).  After differntiating DOCTYPE from comment I
stupidly allowed DOCTYPE token to pass through misplace-content handling code.
In doing so, the DOCTYPE token opened up a BODY and therefore did not open
FRAMESET/FRAME.

Checked in a fix.
Resetting QA contact from leger.
Status: RESOLVED → VERIFIED
The problem is not occuring with the Nov 19th build on Windows 98 and Linux Red
Hat 6.0 or on the Nov 17th Mac OS 9.0 build. Marking verified fixed.
