Checked into GIT, the multilib x265_hidepth options change as provided by Andrew.  It did compile on Fedora 42 finally -- the laptop may have overheated causing me 3 times in a row to end up with compiler, internal, or segmentation errors.

Andrew, thanks for rebasing but the error was mine because I had applied the patches to Makefile manually and missed a closing parenthesis.  So it works just fine on the older Fedora.  But I keep getting segmentation compiler error on fairly new Fedora 42 when compile hidepth, which I think was mentioned somewhere in the mailing list.  Will look at tomorrow.

Changelog for x265  4.1 (nearly 1 year old but still latest) mention some compilation issue on clang.

You can try to upgrade our copy to 4.1 and see how ( if )  it  improves situation on fedora  42.

With the last 3 patches, I can disable h265_high_depth: to compile is faster and rendering at more than 8-bit depth is not possible.
Using the 3 patches but not using the “--disable-x265_hidepth” flag in ./configure, compilation works fine, the time is shorter, and I can render at 10-12 bits.
That's OK for me.
