Package: gnuplot
Version: 4.2.2-1.1
Severity: normal
gnuplot crashes when setting a label which uses formatting characters
that goes off the page.
Following gnuplot script can reproduce the error reliably on my system:
----
m = 1.2345678901
set label sprintf('%10g %10g %10g %10g %10g %10g %10g %10g %10g %10g %10g
%10g', m, m, m, m, m, m, m, m, m, m, m, m) at graph 0.05, 0.95
plot sin(x)
----
And the error message I get when the gnuplot crashes is:
----
*** glibc detected *** gnuplot: double free or corruption (!prev): 0x09429198

----
This error doesn't appear to be that critical since no one would
actually want to set a label so that it goes off the page, but in that
case, gnuplot should output an appropriate error message rather than
crashing with some memory error.

Andrzej
