Description Michael Meeks 2012-05-14 06:43:47 UTC

I guess this is thread related, and rather unusual, since I can only reproduce it under valgrind, and only when the machine is under load under valgrind ;-)

Comment 1 Stephan Bergmann 2012-05-14 07:02:43 UTC

The main thread is probably already in exit(3) when the filter::config::LateInitThread is only starting to run in your high-load scenarios.  This is a known problem of that LateInitThread, see "TODO: a protocol is missing how to join with the launched thread before exit(3), to ensure the thread is no longer relying on any infrastructure while that infrastructure is being shut down in atexit handlers" at <http://cgit.freedesktop.org/libreoffice/core/tree/filter/source/config/cache/lateinitlistener.cxx?id=8b960f0ec4ac13a98d8b1c33cf23ef82cc5b6841#n114>.

Comment 2 Joel Madero 2013-07-25 16:34:29 UTC

@Michael - should this still be open? If so can we set it to NEW?

Comment 3 Michael Meeks 2013-07-25 17:22:23 UTC

I guess so - Stephan confirmed it as a known issue :-)

Comment 4 Caolán McNamara 2014-09-28 15:22:07 UTC

LateInitThread has been removed, so this exact problem cannot happen anymore
