Description
When the ICU library is used for date formatting in format-date() (etc), there is a multithreading bug that may cause the wrong month-name or day-name to be output.
(Specifically, instances of the ICUNumberer class are reused and shared across threads, but the class has an instance-level field "cal" which is mutable.)
The observed effect is that XSLT3 test validation-0202 produces incorrect output in about 1 in 30 runs.

Turns out the problem is a bit harder to fix than I thought: the ICU class SimpleDateFormat turns out not to be thread-safe.
