Issue 25191: test_getsetlocale_issue1813 failed on OpenBSD

Hi,

the test test_getsetlocale_issue1813 in ./Lib/test/test_locale.py failed on OpenBSD:

======================================================================

The first setlocale(locale.LC_CTYPE, 'tr_TR') works fine, but loc = locale.getlocale(locale.LC_CTYPE) then locale.setlocale(locale.LC_CTYPE, loc) does not work.

Attached is a patch to skip the second part if it does not work, is it correct?

Thanks,

Remi.

The problem with this patch is that the second assert is the point of the test.  Do get/set_locale work in the TR locale?

Although this issue came first, I am closing it as a duplicate of #37945 as the latter has extensive, but to date inconclusive, analysis and discussion.
