Bug Description

This consistently fails if # sign is removed from those the lines.
With the lines commented (as is) gnuplot -p functions correctly.

On gnuplot 4.2, patchlevel 6 as in Ubuntu Lucid 10.04 LTS, it functions correcly, even for the gif.

reason found: this version of gnuplot does not handle overflows in cbrange well.
The log scale, then set to .1 to 500, overflows on the -20 values.
This causes the crash.
