Original bug ID: 7567
Reporter: Richard Jones
Assigned to: @Octachron
Status: resolved (set by @Octachron on 2017-06-26T12:31:19Z)
Resolution: not a bug
Priority: normal
Severity: minor
Platform: Linux x86_64
OS: Fedora
OS Version: 27
Version: 4.04.2
Category: standard library
Monitored by: @gasche "Richard Jones"

Bug description

This happens with both OCaml 4.04.2 and with OCaml 4.06 from git. Simply run the test suite, and it fails at:

... testing 'sorts.ml': ocamlc Error: results don't match reference output!

This works on Fedora 26, but fails on Fedora 27. The major difference could be updated glibc. I'm not sure what else would affect this test.

Fedora 26 (working):
glibc-2.25-6.fc26.x86_64

Fedora 27 (failing):
glibc-2.25.90-12.fc27.x86_64

Steps to reproduce

make -j1 tests

Additional information

The full output of the test is attached.

Sorry, this is a bug in glibc after all. memcmp was broken: https://bugzilla.redhat.com/show_bug.cgi?id=1464403

Fixed by upgrading to the very latest glibc.

Please close this bug.
