I have been made aware of a bug in the krb5-1.5 version of the GSSAPI
library. This bug causes "g_initialize.c:97: gss_release_oid: Assertion
`(&(&_m->os)->n)->initialized == K5_MUTEX_DEBUG_INITIALIZED' failed."
crashes in the UW imapd and ipop3d servers that are built with this
version of Kerberos, e.g.,
% telnet localhost pop3
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
ipop3d: g_initialize.c:97: gss_release_oid: Assertion
`(&(&_m->os)->n)->initialized == K5_MUTEX_DEBUG_INITIALIZED' failed.
Connection closed by foreign host.

This is not a UW imapd bug; it is a bug in Kerberos internals in 1.5.
The Kerberos developers have acknowledged it, and produced the patch
listed below to the Kerberos 1.5 sources. This fix will be in krb5-1.5.1.
Hopefully, this posting may save other sites from the problem.
This problem is specific to krb5-1.5 and does NOT affect earlier versions
of Kerberos.
