samba - Jul 2012 - Samba 3.6.x: smbd receives sigpipe and crashes

Hello,
I've got problems with Samba 3.6.0 up to 3.6.6. Forked smbd processes 
are closing unexpectedly and sometimes smbd server exits. (In Samba 
3.5.16 everything works).
When invoke smbd from gdb and turn off SIGPIPE passing (by command 
"handle SIGPIPE nostop nopass") everything works fine. I found out
that
SigBlk flag of forked smbd processes in /proc/*/status is: 
0000000000000880 and should be 0000000000001880 (It works in Samba 3.5.16).
This flag changes after invoking getpwnam function, after passing string 
"guest+workgroup" to it.
There is probably a memory leak or something.

Does anyone have similiar problem?

Thank you in advance

What platform are you running Samba on ?
