Bug#743247: gnuplot: Running load destroys arguments from call

[Matthew Wakeling]

Package: gnuplot
Version: 4.6.4-1~bpo70+1
Severity: normal

Dear Maintainer,

When running a "call" command with arguments, if the called file runs a "load" command, then the arguments are destroyed.
For example, if there are three files in the current directory:

experiment.plot:
set samples 1000
set pointsize 2.5
call "experiment.plotcall" "1"

experiment.plotcall:
load "experiment.plotload"
set terminal postscript eps monochrome enhanced dashed dashlength 2 22 size 6.6in, 4.45in
set output "experiment.eps"
plot 'flibble$0.out'

experiment.plotload:
<empty file>

then the command "gnuplot experiment.plot" is run with version 4.6.4-1~bpo70+1, then the following error message will be given:

"experiment.plotcall", line 6: warning: Skipping unreadable file "flibble.out"
"experiment.plotcall", line 6: No data in plot

whereas with version 4.4.0, the following error message is given:

"experiment.plotcall", line 6: warning: Skipping unreadable file "flibble1.out"
"experiment.plotcall", line 6: No data in plot

Note that the argument "1" has been destroyed. If the "load" command is removed from experiment.plotcall, then the argument is preserved.
