Follow-up Comment #4, bug #55071 (project octave):
Running under gdb, the interesting part of the backtrace is
#0 0x00007f0c2c3dfe95 in cntr (X=..., Y=..., Z=...,
lvl=-0.99992325756410083)
at libinterp/corefcn/__contourc__.cc:277
#1 0x00007f0c2c3e0293 in F__contourc__ (args=...) at
libinterp/corefcn/__contourc__.cc:315
__contour__ is an internal function and doesn't do input validation. I will
prepare a patch for the upstream contourc.m to make sure that there are at
least 2 rows and 2 columns in the input data.
