Thanks for the report.  This problem has been recently fixed upstream by:

commit 20f0d60db4fb5083779c4c9182bbc692f7d2bac5
Author: Tom Tromey <tom>
Date:   Fri Oct 5 14:54:35 2018 -0600

    Avoid crash when calling warning too early

I'll backport the patch and release a new Fedora GDB with it soon.
