-/* Verify that strcoll does not crash for large strings for which it cannot
-   cache weight lookup results.  The size is large enough to cause integer
-   overflows on 32-bit as well as buffer overflows on 64-bit.  The test should
-   work reasonably reliably when overcommit is disabled, but it obviously
-   depends on how much memory the system has.  There's a limitation to this
-   test in that it does not run to completion.  Actually collating such a
-   large string can take days and we can't have xcheck running that long.  For
-   that reason, we run the test for about 5 minutes and then assume that
-   everything is fine if there are no crashes.  */
