regression: gnuplot crashed with SIGSEGV in terminal gif

[jan]

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.

The bug is NOT present when forcing the packages
gnuplot_4.6.0-8_all.deb
libgd2-xpm_2.0.36~rc1~dfsg-6ubuntu3_amd64.deb
gnuplot-nox_4.6.0-8_amd64.deb
libgd2-xpm_2.0.36~rc1~dfsg-6ubuntu3_i386.deb
gnuplot-x11_4.6.0-8_amd64.deb
 from the quantal distribution onto my precise system.

but, in dping so, I had to replace the packages below, and after that gthumb throws lots of warnings.

fontconfig_2.10.1-0ubuntu3_amd64.deb
fontconfig_2.10.1-0ubuntu3_i386.deb
fontconfig-config_2.10.1-0ubuntu3_all.deb

[jan (jan-ubuntu-h-i-s)]

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.
