imap crash [@ operator new(unsigned int) | nsThread::PushEventQueue(nsIThreadEventFilter*)]

low cash rate, only crashes recorded are for v3.0, and none in alpha and beta
all are ms-windows
none found for seamonkey or firefox

should this move to xpcom?

-----------------------------------------------------------------------------
there are couple variations of this crash. most involve nsImapProtocol::ProcessCurrentURL

 The simplest is nsImapProtocol::ProcessCurrentURL - nsImapProtocol::ImapThreadMainLoop like

so no 3.0.x ?

Comment 2

[Wayne Mery (:wsmwk)]

yes all v3. probably too low a crash rate to see in v3.1

Comment 3

[timeless]

no, you can fix this (in theory) by using CPP_THROW_NEW

Comment 4

[timeless]

oops, sorry, i assumed mailnews was allocating, yeah, this goes to xpcom, but note that their plans for fixing such things are ... "interesting".

Comment 5

[Wayne Mery (:wsmwk)]

no crashes after 3.0.x
