memory leak

[Piotr Orchowski]

Hi

I'm getting momory leaks when trying to use pl_laberl_r, pla_alabel_r
functions:

(void)pl_alabel_r(plotter,'c','c', s);
(void)pl_label_r(plotter, s);
(void)pl_label_r(plotter, (const char *)s);

where s is:
char s[10];
 sprintf(s, "%d",some_int_number);

============

Looking at the documentation I'm using those functions correctly.

plotutils version:
(GNU plotutils) 2.5
