when building CLK(either SDL or QT) from either upstream or the pkgbuild with GCC errors out with a segmentation fault in cc1plus. i have test and the program will build fine when using GCC 15.2.1 or using the latest version of clang. i have test to see if the problem is fixed by going to a newer version by git cloning the git repo, that did not fix it.
Looks to be a gcc regression causing infinite recursion while generating and evaluating an implicit move constructor. I would suggest opening an upstream issue if there is not one open already.
by upstream are you referring to the CLK project or GCC?
gcc as the compiler should only ever fail with an internal error due to a hardware issue. As I can reproduce the issue on a separate system and you observed the issue is not present in gcc 15 that points to a gcc 16 regression. CLK might be able to work around the issue by adding an concrete move constructor.

I am experiencing something similar and opened https://gcc.gnu.org/bugzilla/show_bug.cgi?id=125455, but they couldn't reproduce it. Maybe you could reply to that ticket?
