0.15.3 - error: cast to smaller integer type 'enum script_record_format' from 'const void

[AngryPenguinPL]

When compile 0.15.3 I see this error: cast to smaller integer type 'enum script_record_format' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] Worth to add 0.14.1 compile without issues.

OS OpenMandriva Cooker Compiler: Clang 11

Build log with error:

This line was added in 2014 in commit 95b65647e0d1, so I rather suspect it's some new clang version that causes the new warning?

Anyway, I can reproduce this with clang on Fedora, I'll add that to CI and fix it, thanks for the report!
