Forwarded krb ticket causes crash in Version 4.0.0alpha17-GIT-2d23dff

[Lukasz Zalewski]

Hi list,
Our attempts to use a forwardable krb ticket result in a crash. Below is 
a sniplet of the log entry:

[2011/08/01 16:29:10,  3] 
../source4/auth/kerberos/krb5_init_context.c:69(smb_krb5_debug_wrapper)
   Kerberos: TGS-REQ user at MYDOM from ipv4:xxx.xxx.xxx.xxx:xxxxx for 
ldap/myldaphost at MYDOM [canonicalize, renewable, forwardable]
*** glibc detected *** /usr/local/samba/sbin/samba: malloc(): smallbin 
double linked list corrupted: 0x0000000002c27cd0 ***

Please let me know what other debug information i should provide

Regards

Luk
