If an xpicleanup.dat file is present, Seamonkey 1.1a won't start.  Attempting to run xpicleanup manually yields a crash:

Process dumping was disabled, use DUMPPROC / PROCDUMP to enable it. 

There is speculation that there is a bug in the libc06 spawn/exec*() implementation.  Another user reports that it works on trunk build from 2 days ago; not sure if that is a libc05 or lib06 build.

Setting initial state to unconfirmed, as I have yet to see anyone else confirm that they see this.

Just for the record, it is a libc06 trunk build that I was referring to.  
Comment 2 User image Peter Weilbacher 2006-09-30 01:24:27 PDT
Yes, the same crash happens here, but that doesn't look like it can be caused by the libc06 implementation of spawn/exec*().

From the address it seems to crash in PerformScheduledTasks().
Comment 3 User image Peter Weilbacher 2006-09-30 01:38:31 PDT
It does not crash when called as ".\xpicleanup" instead of just "xpicleanup". The logic to strip off the path in InstallCleanupOS2.cpp is flawed.

But I think the real problem is that xpicleanup does not get called correctly from SeaMonkey, and not that it crashes when called in a wrong way.

Correct crash when backslash is missing

This adds another safeguard to xpicleanup in case there is no backslash in the path. It includes the same change in the Windows code, but as I don't have Windows I cannot test and don't know if it is even necessary.
Comment 5 User image Peter Weilbacher 2006-09-30 01:59:05 PDT
Just for the record, the same crash occurs on trunk (and probably on Windows), too, and it has nothing to do with PerformScheduledTasks().

Thanks for the reviews. Fixed on trunk.

Correct crash when backslash is missing

I think we should finally get this into branch, too.   At least for OS/2 this is an annoying problem and the fix hasn't caused a problem in the last 10 months.

Comment 11 User image Peter Weilbacher 2007-09-03 15:53:07 PDT
Verified as fixed on OS/2 with the SeaMonkey 2007-08-31 branch nightly. Leaving as fixed1.8.1.7 for Windows verification.

Peter: Can you verify this Bug also for, since i don`t have a OS/2 System ?
Comment 13 User image Peter Weilbacher 2007-10-19 16:02:34 PDT
That's what  I said in comment 11. :-) Assuming that Carsten's comment means that verification was done on Windows, I now mark it verified.
