Description Thomas Munro 2016-03-24 19:37:16 UTC 
The man page for strxfrm says:

"Comparing two strings using strcmp() after strxfrm() is equal to compar-
ing two original strings with strcoll()."

The PostgreSQL hackers wrote a test program to study a collation bug
on another operating system.  The test generates random strings and
checks if strxfrm and strcoll agree on their ordering, according to
each locale available on the system.  I decided to try it out on
FreeBSD and found that it passes on 10.2, but fails miserably on
11.0-CURRENT.

The test program is here:

Filed as 'standards' because POSIX requires strxfrm and strcoll to agree, but please move to the correct component for libc bugs if appropriate.

This should be fixed in base r317034.
