1 year ago As can be seen from the error message, the compilation error happened in the testing framework Catch2 src/extRegression/catch.hpp.
Updating this file to v2.13.10 fixes the problem.
GCC seems to complain about arrays being associated with non-constant sizes. GCC behavior seems to have changed recently. C++ standard seems to require the sizes to be constant, but GCC has earlier allowed non-constant sizes.
$ gcc --version gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0
