This is a bug in plot3d.c. In the switch starting at line 632, the case
"(j == DF_FOUND_KEY_TITLE)" is not taken into account.

It is triggered by setting:

"set key auto column", either just before the splot command, or in the
.gnuplot file (that's where I found it).

setting "set key noauto" gives back a normal behaviour.

DF_FOUND_KEY_TITLE is set in datafile.c, but I could not deceipher the logic.

I guess that "auto title" is handled properly for 2D plots, but was not
completely checked for 3D. I turned the crash into a nasty warning by
adding (line 633):
if (j == DF_FOUND_KEY_TITLE) break;

(I get complains about limits not set), but that's not a patch.

Cheers.
