Bug in libplot 2.4.1

[Roman Putanowicz]

Hi,

I would like to report a bug (at least in my understanding :-)
in libplot library (version 2.4.1).

The bug is in file libplot/g_pagetype.c line 103:

100    success = true;
101    break;
102      }
103    free (viewport_pagesize);   
104
105    if (success)

In this line the memory for viewport_pagesize is freed 
but in subsequent lines this memory is inspected
through the 'next' pointer :-(

Unless the viewport_pagesize is not modified everything
so this is hard to spot but I had this "lack" to be bitten
by it.

Thus if one moves memory freeing just before return 
everybody will be happy :-)

Regards

Roman Putanowicz
