Created SDL tracking bugs for this issue:

Affects: fedora-all [bug 1732251]

Comment 2 Petr Pisar 2019-07-23 11:40:12 UTC

The bug is in SDL2_image component. Not in SDL component. I moved the bug there. Please be more careful when filing bugs.

Comment 4 Riccardo Schirone 2019-09-20 14:01:41 UTC

Statement:

This issue did not affect the versions of SDL as shipped with Red Hat Enterprise Linux 5, 6, 7, and 8 as they did not include SDL2_Image add-on.
