Dima,

thanks for looking again.

I can't judge on the details because that's been Jean-Sébastien's doing,
but I know that darktable uses two compilers:
- one is for the C++ librawspeed and the C darktable code, and
- the other compiler shall be LLVM to compile the OpenCL kernels.  I
don't think GCC could do the latter, and certainly darktable expects to
use LLVM by way of its build tooling and configuration (cmake-based).

Jean-Sébastien switched the C/C++ compiler from LLVM to GCC.

If that raises conflicts, I wonder what those would be, and what to
watch out for in the logs or at run-time, and that a "make reinstall" or
"poudriere bulk -tC" would not catch. Both Jean-Sébastien and I,
independently, have successful builds with both GCC and LLVM.  I have
not yet tested OpenCL at run-time though.

So...?

Cheers,
Matthias
