Status: RESOLVED DUPLICATE of bug 231995

(Core :: XPCOM, defect)

Description

[timeless]

Product ID      Gecko1.4
Build ID        2003062408
Trigger Time    2003-06-30 23:28:04
Platform        Win32
Operating System        Windows NT 5.0 build 2195

AddNullTerminator [d:/builds/seamonkey/mozilla/string/obsolete/nsStr.h,
line 350]

Steps:
run talkback now (you can't afford for talkback to try to launch /after/ 
mozilla runs your system out of memory :)
get your system to have say less than 10mb of vm available
run mozilla many times (probably over 100)

observed outcomes:
* errors from the pref service (sometimes with message text, sometimes without, 
sometimes with a really wide dialog, usually system default narrow)
* mozilla will just quit
* mozilla will cause an access violation or an unknown software exception
* mozilla hangs (using ~7mb of vm)
* mozilla will crash and trigger talkback, including here.

Changing summary, although I suspect they're the same (union)

610ec98c 6683244800       and     word ptr [eax+ecx*2],0x0

The above was the crash instruction. ecx was 0x0. eax was valid. Which means the
"if" was true, and it was doing the unicode calc.

Neither the file, nor the function quoted exist in the repository anymore.
