I was not able to reproduce this problem, either with my own build of GNU Make 4.4.1 or with a binary extracted from the RPM from the link you provided. I tried running under valgrind and with a binary compiled with ASAN, with and withoug debugging enabled, ran the test 1000 times. I also tried GNU Make 4.4. If you can generate a coredump please examine it with GDB and send along at least the backtrace. -- Paul D.
