I'm compiling m4 1.4.19 on a dual-socket server with second-generation AMD Epyc processors (128 cores total). I'm compiling using GCC 12.2.0. "make -j128 check" fails, but "make check" succeeds. While troubleshooting, I noticed that the test reads an empty file instead of one containing the expected number of bytes. I'm guessing that another test (running concurrently) is interfering with the results of this test.
Is this a known issue?
