Subject: Little warning for endgame tablebases

Author: Tony Werten

Hi all,


when checking my own tables, I found out that the following (illegal ) position,
causes the Nalimov code( rather, the decompresssion code ) disabled further egtb
probes.

No problem for normal use, just when you're doing something without checking if
the position is legal, it goes wrong.

The position looks like it might have been optimized away, causing a probe
beyond the uncompressed size of the filechunck just read in, causing an
"invalid" flag on the tablebase, resulting in a disabling of the KNNkp
tablebase.

[D]4K3/8/8/k7/8/1N6/p7/N7 w - - 0 0
