--- Comment #7 from Stephen Fisher <stephentfisher@xxxxxxxxx>  2008-04-04 05:30:22 GMT ---
The fix for the LDAP portion of bug #1113 ("Several crash when SE_DEBUG_FREE
used") appears to have introduced this bug.  The crash is occurring in the
ldap_reinit() function at the g_free(ldap_info) function call (I can tell
because when I comment that line out, the crash no longer happens):

wireshark(47255) malloc: *** error for object 0xc1cb0cff: Non-aligned pointer
being freed
*** set a breakpoint in malloc_error_break to debug

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0xc1cb0d07
