The problem is, that the heimdal implementation of kerberos5 used on
sles8 needs an extra include statement for com_err.h in
src/interfaces/libpq/fe-auth.c to get the prototype for
error_message(), while on newer SUSE-releases using the MIT Kerberos5
implementation this prototype is provided by krb5.h itself.

So I suspect this bug might hit everyone using heimdal, but it only
gets triggered when one of the calls to kerberos in
src/interfaces/libpq/fe-auth.c returns with an error.

I am still not sure why the crash only happened on x86_64.
