gdb bt full
Intermittently, samba w/ winbind integration crashes during an ls -lha / getfacl of a file.
Before the crash, owners are listed correctly (e.g. as their samba "DOMAIN\user"). After the crash, many calls hang, and ls -lha takes 10-15+ seconds.
This is compiled from the recent git:

Attached is a gdb backtrace.
Note that this is just before the patch for bug 9832, though I don't see the same "Bad talloc" signature in the backtrace.
This happens pretty frequently with "ls -lha" when looking at files owned by AD DC users. This seems to happen 100% of the time with "getfacl" on AD DC-owned files, though I'm trying to make a cleaner test case.
I'll attach a second bt full from a repeat crash, in case it's helpful.

Hm, I think this crash is related to bug #9853
I noticed "krb5_cc_store_cred" in this trace, but from the logs I also see:

Appears fixed as of latest version ~ commit 596b51c666e
