121619 - Mozilla crash corrupted component.reg => Mozilla cannot be started again

Status: RESOLVED DUPLICATE of bug 72518

(Core :: XPCOM, defect)

Description

[Vincent Deconinck]

From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (Win98; U)
BuildID:    2002012304

On my heavy loaded Win98 PC (Moz + IE + NS4.77 + a few Java VMs with only 128 Mb 
RAM), Mozilla crashed the system (endless Blue Sceens Of Death) - no talkback. 
But OK, I am the one to blame as one shouldn't overload a Microsoft OS in such a 
way.
Unfortunately, upon reboot, Mozilla wouldn't restart, crashing everytime I tried 
with a standard Windows dialog-box (This program has performed an illegal 
operation ... The full text is reproduced at the end of the report).
To diagnose whether the problem was with my profile or with the bin/ directory, 
I re-unzipped the nightly in another dir and renamed it, and Mozilla started 
again.
Looking further by comparing all the files (thanks cygwin), I noticed that 
bin/component.reg had changed. I thus restored that file from the freshly 
unzipped dir to the original one and Mozilla started again, so obviously the 
first crash had left component.reg in such a state that it crashed Mozilla on 
startup, leaving the user in a deadlock...
Maybe a quick test on component.reg's status would be helpful...

Reproducible: Always
Steps to Reproduce:
1. Put a corrupt component.reg (attached, zipped) in the bin dir.
2. Try to launch Mozilla


Actual Results:  Crash

Expected Results:  Mozilla could detect it wasn't shut down properly last time 
it ran, and run a few tests so that corrupt files are repaired or restored...

This bug is not about the first crash, but about the fact that if Mozilla is not 
shut down properly (the cause may have nothing to do with Mozilla), it can 
result in the impossibility to start it up the again afterwards...

->installer

Comment 4

[Henrik Gemal]

not installer...
xpapps perhaps?

Comment 5

[Daniel Veditz [:dveditz]]

->XPCOM Registry. Somebody's not calling flush on the registry most likely,
after install time there shouldn't be anyone writing to this file.

this sounds like a duplicate.
