In kcm/cache.c in kcm_ccache_alloc(), slot->kdc_offset is not initialized. The means that kcm will return an uninitialized values for GET_KDC_OFFSET (the value will often be 0, but sometimes some random value) unless SET_KDC_OFFSET has been called for the cache before.
This has been fixed upstream on the master branch, but not on heimdal-7-1-branch:
