Hi, We've had to workaround this in meson's CI by skipping the test for Ubuntu (https://github.com/mesonbuild/meson/commit/9c3dcea2cda3b6eff90e72a826196bfb44d151d8). This is a nasty problem for anyone trying to build openmpi+fortran projects on Ubuntu with meson. Is there anything we can do to help?
