Re: [Bug-XBoard] [bug #48571] Error after selecting new engine.

[h . g . muller]

Well, when I start XBoard in German and load GNU Chess through the menu
dialog it also works.

Can you start XBoard as "xboard -debug" and load GNU Chess (presumably
causing XBoard to exit), and then send us the created xboard.debug file?
Perhaps that will shed some light on the matter.

It is very strange that selecting the engine from the command line (with
-fcp) would make the engine behave differently than when selecting it from
the dialog. (In fact OK'ing the dialog will just create a line "-fcp XXX"
for the given engine command, and process that if it were the command
line.) The only explanation I can think of so far is that you have
multiple versions of GNU Chess on your system, (and that you browse to a
different one than what would beinvokedwhen just typing the command), and
that some of those crash in certain locales.
