169236 - resource/memory failure [@ SetFont(...aFont=0...)] in Phoenix

Status: RESOLVED INCOMPLETE

(Core :: Layout: Text and Fonts, defect)

Description

[timeless]

Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.1b) Gecko/20020912
[Phoenix]

p133, 32mb ram, 0 mb free disk space (swap had grown to fill the disk, so i
suspect that the os ran out of memory)

I didn't have drwatson running and i didn't have talkback because phoenix
doesn't do that. The crash happened after i had stopped a bugzilla page load and
decided to go back or forward, i was using 3 tabs (the window had 5 tabs at some
point in time).

I sent dbradley the windows crash output and he was able to connect it to a
specific line of code.

Essentially we believe that an allocation failed for the aFont parameter to SetFont.

[David Bradley]

The crash is occuring on line 1924 of nsRuleNode.cpp

aFont was null at this point and that caused the crash. The most I can tell is
that nsRuleNode::ComputeFontData called SetFont, using font. Given timeless's
comment this was an out of memory condition and the code didn't check the final
new for font.

Here's the crash data Timeless had:

Comment 2 blames "out of memory condition" so I'm guessing this is something
that we'd intentionally abort for these days.
