heimdal 7.8 crash (in OpenLDAP) with spnego/ntlm, is this familiar?

[Nadezhda Ivanova]

Hi team,

An OpenLDAP user encountered this issue, and since Samba also uses 
Heimdal too, we were wondering if maybe it has happened in Samba as well 
and was fixed? Do you think it is something that can affect Samba? There 
are back traces in the issue but no steps to reproduce, it seems to 
happen randomly in their environment, and we haven't had any feedback 
from the Heimdal team yet.

I could not find a relevant issue in the Samba bugzilla or the commits, 
but perhaps one of you remembers something?

Many thanks,

Nadya
