Comment 9

[Eric Hodel]

I'm getting the same stack trace as bug 112133:

#0  nsComponentManagerImpl::FreeServices (this=0x0)
    at /disks/current/moz/mozilla/xpcom/components/nsComponentManager.cpp:1918
#1  0x281ab600 in NS_ShutdownXPCOM (servMgr=0x0)

#2  0x8051764 in main (argc=1, argv=0xbfbff974)
    at /disks/current/moz/mozilla/xpfe/bootstrap/nsAppRunner.cpp:1633

As its duped to this one, I'm reopening this bug.

The difference is I'm running FreeBSD:

...
checkout finish: Sun Feb 24 11:52:08 PST 2002

This is a crash on startup.

Core dumps ready for degbugging :)

Comment 10

[Eric Hodel]

A clobber build fixed my problem, but I did step through and found that in
main1() in nsAppRunner.cpp, it would return at line 1161 after:
nsCOMPtr<nsIObserver> startupNotifier =
do_CreateInstance(NS_APPSTARTUPNOTIFIER_CONTRACTID, &rv);

failed.

Apparently this is the result of a bad build, and should probably return to
being resolved fixed.

Comment 11

[basic]

so this is fixed/wfm?

Comment 12

[Roland Mainz]

Marking FIXED again per comment #10 ...
