Description of problem:
got this alert after trying the test program proposed by https://bugzilla.redhat.com/show_bug.cgi?id=1370475#c23

SELinux is preventing /home/sheepdestroyer/a.out from 'create' accesses on the file /dev/fd/.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that a.out should be allowed create access on the  file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'a.out' --raw | audit2allow -M my-aout
# semodule -X 300 -i my-aout.pp
