--- Comment #3 from François Gouget <fgouget at codeweavers.com> ---
You are right: this failure does not happen anymore on the
newtb-debiant2-win32-ar-MA test configuration.

However I still see the same failure on my (Debian+KDE) test machine (fg-deb64)
though it's pretty rare (happened on 2021-10-25 and 2021-11-30). It also
happened once on newtb-debiant2-win32-ja-JP on 2021-08-09.

I also cannot reproduce the failure on my machine in the ar_MA.UTF-8 locale
when compiling Wine from one of the commit ids where it should be systematic
(b99d7db835b8..aa629c4c7225).

So I think we have two options:
* Run the test in Valgrind in the hope that the output is usable and points to
the source of the buffer overflow.
* Mark the bug as "Works for me" and reopen it if/when the failures happen
again, even if intermittently.
