    _______________________________________________________

Details:

The function "movmean" intermittently uses very large arrays for reasonably
sized input.
IIUC, Rik suggested in bug #59599 to implement (at least that part of) the
function in C++ which could use a loop instead of the large intermittent array
without a performance penalty.

Opening a bug report to not forget about that.
