- Date: 04 Mar 2003 17:08:12 +0200
Package: Evolution
Priority: Normal
Version: 1.2.2
Synopsis: Double SEGV and deadlock [SMP]
Bugzilla-Product: Evolution
Bugzilla-Component: Mailer
Description:
Threads 3 and 1 both receive a SEGV. Thread 1 is in libc free()
function. Post mortem on thread 3 indicates that e_mempool_new() may be
returning a garbage pointer. The application deadlocks attempting to
display gnome crash dialog.
