Description Florian Weimer 2022-11-22 11:21:54 UTC 
nacl changes the FPU control word using fldcw, but never changes it back. This corrupts the FPU state and may cause the rest of the process to produce incorrect results.

I don't know of any concrete problems. Maybe no users of this package are left. I found this because the package was flagged during C99 porting.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 38 development cycle.
Changing version to 38.
