I pushed a patch for test 114.
On old libc there seems to be a race condition with stdio and fork().
I could reproduce the problem (after about 1000 runs) on i686 with old
fedora release.
I can not reproduce the problem on my current x86_64 machine with latest
fedora.

Hi Herman,
I quickly replaced __APPLE__ by __clang__ in 114 test but, as this
test is not reproducible, I can’t say it is the right fix to apply.
I ran changes locally on Debian x86_64 and RPi Debian 32 which passed
114 test.
Is it annoyed to have do_fork thread always executed?

Hi again Herman,
I continue to test mod with your latest patch on the (many) machines I
have.
This time, it is a Debian 10.6 x86_64 fully up to date and, guess
what?, it fails on test 114 with clang 7.0, (gcc worked).
See log below:
