Talkback is coming up on exit in today's linux commericial build. I can't
actually tell if it's a crash on exit, or just a bug in talkback, but it doesn't
look like a crash.

This is 092408 build.

crash on exit might be harder to view...
if this is new, might be related to dp/dveditz changes over the weekend.
can we get a stack trace produce by talkback?

This is all I get out of the talkback report (linked to above):

 Trigger Type:  Program Crash

 Trigger Reason:  SIGSEGV: Segmentation Fault: (signal 11)


 Call Stack:    (Signature = 0x4049c45c f8028444)

   0x4049c45c


   libc.so.6   0x17cb9 (0x401e1cb9)

The shutdown crash I saw on my linux machine was due to CNavDTD statics. Kipps
checkin was supposed to fix that.

This is the static dtors triggering. I suppose this can happen on release builds
too. These have been in the tree forever and some of us see them.

I am building now. Will confirm this theory.

Is there a reproduicble steps or Launching and Shutdown should crash ?

launch and shutting down will do it. as dp said, maybe this has been around
forever, but we really don't notice it on release builds.

Yup I crash after main returns. And the stack trace looks so much like the
static destructor thing.

Ramiro is debugging this. He already has a patch for one of the instances of
static in CNavDTD.cpp Thanks ramiro.

This actually isn't happening on 9/29 M10 build, i.e., talkback is not coming up
on exit anymore. However, I'm not sure if ramiro is looking at something else,
so I will leave this bug open and let him or dp mark this resolved...

I did see talkback come up on exit on Win32 using the 1999093012 build.

XPCOM was fixed to not unload dlls on exit. That fixed this as the problem was
static dtors firing.

Let us mark this fixed and open a different bug for static dtors.

Ramiro ok ?

Cpratt, core dump on exit on windows should be a separate bug if you are seeing
it.
