Subject: segfault when unloading libraries on old O/S
Date: Thu, 21 Jul 2011 20:14:53 +0000
We've had this in our local source for a long time and it's to prevent a segfault when unloading libraries on RHEL 2.1. I don't know whether anything else needs it. The original description and patch are below.

"There must be a bug in the loader on RHEL 2.1. libcom_err's destructor is sometimes (not always) called before libgssapi_krb5's destructor. This causes libgssapi_krb5 to look at the already freed global table.

The fix is to NULL out et_list once it is freed, so that even if libgssapi_krb5's destructor is called afterwards, it will not look at the list."
