It happened on linux machine.
here is "uname -a"  2.4.20-20.9 #1 Mon Aug 18 11:45:58 EDT 2003 i686 i686 i386 GNU/Linux

Codes are from latest ethereal branch. I made it by myself. I attached back trace here.

To reproduce it, select Preference-> Protocol -> Mapi Decrypt MAPI PDUs, ethereal crashes
sometimes, not always, seems crash once the other time.

I also attachmented a mapi traffic here too.

What should I do when I make ethereal so that it would show real function names instead
of ?? when I backtrace core in gdb?

Also, the latest ethereal windows version seems have problem with "follow tcp stream" .
