Here's what I see in audit.log after make check on a machine with
selinux in permissive mode:

type=AVC msg=audit(1495455280.802:2565): avc:  denied  { execheap } for  pid=2256 comm="test1" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process permissive=1

I attempted to make various things work with selinux before giving up,
so there may be more to report in a default install.
