Hi,

I've been playing around with FEN positions in 5.07, and discovered a
segfault problem - not exactly a bug, but it could be friendlier.

If you load in a FEN position where white has black in check, and the turn
flag indicates that it's white's turn, GNU Chess segfaults. On the one
hand, this is quite reasonable, as it's an impossible position to get into,
but on the other hand the error could be handled more gracefully. I've just
spent ages trying to automate GNU chess for a series of FEN described PGN
books, only to suffer crashing on every other file and having no idea why -
the solution dawned on me this morning and left me feeling like an idiot.

This seems to happen either through a .epd file or when the FEN is specified
as part of a PGN book.

BTW, is 5.07 officially released? Gentoo seemed somewhat suprised when I
pointed out to them that it's been out since august, and the webpage at
gnu.org still isn't updated.
