--- Comment #1 from Anton Shterenlikht <mexas at bristol dot ac.uk> --- On Cray seems to run fine too. Sorry for crooked rushed English. The code itself is very simple, so should be clear what's going on. But I think if I put all code in a single file, then I cannot reproduce the error anymore. Thanks!
