Comment (by raimue@…):

 I rebuild heimdal with debug symbols enabled (`configure.cflags-append -g
 -O0`) and here is a backtrace from this run:

 {{{

 }}}

 So the problem appears to be that the Kerberos.framework gets called here
 for the `ccache_destroy` symbol, which then calls `krb5_cc_destroy` from
 the Kerberos.framework as well. This leads to a segmentation fault, most
 probably because the opaque data types do not match.
