Hello !

Has anyone out tried gnuchess on a Linux box ? 
There is an annoying bug in either the Linux
libc or in gnuchess.
This is for all versions since 4.0 pl xx (I don't know, when
I started to try this - could be 1 1/2 years )
up to patchlevel 70 with many patches from this group.
If you do a "make test" ( eg: cat ../test/testall|gnuchessr )
the first positions won't  be solved. ( For me it looks like
a problem in stdio - The first 1024 bytes coming to fast ?? )

You got something like this :
Time Target : 0 Total Time 300 and then in the stats line
gnuchess searches only about 15 moves and goes to the next
position.
Last night I played with gdb and it looks like a Problem in
InputPrompt() in the lines with (void) gets(sx) and afterwards.
But the routine looks o.k. to me, if you step over to
EvaluatePosition() /* From memory - it was the routine where the
alpha beta search begins */ gnuchess returns immediately with a
move and XCmoves is {40,0,0}.

Has anyone the same problems on other machines or does anyone
know how to fix this ?

Thanks for your help
Thomas
