Your patch is not a good idea. We don't want to shut down and clean up
after fftw after every execution of the decoder routines. Much
information would need to be recomputed on the next call to the decoder.

This patch solves at least part of the memory leak problem seen with
jt9.exe running under WSJT-X control. jt9 happily passes valgrind
checks running standalone. It's the looping of jt9a causing problems.
In Windows you'll now see the memory usage go up and down whereas before
it would only go up.

I'm using the program below to watch the memory usage of jt9.exe but
WSJT-X keeps pausing the waterfall under my VM so it doesn't run for long.
I'm still seeing random increases in memory once in a while...every few
minutes or so.
e.g. 32k, 24k, 4k, 52k. Still trying to chase those down.
#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <stdlib.h>
int
main (int argc, char *argv[])
{
char cmd[256];
int mem = 0;
int memold = 0;
sprintf (cmd, "ps aux | grep jt9 | grep -v grep");
while (1)
{
FILE *pcmd = popen (cmd, "r");
char buf[256];
while (fgets (buf, sizeof (buf), pcmd))
{
//printf ("%s", buf);
sscanf (buf, "%*s %*s %*g %*g %d", &mem);
if (memold == 0)
{
memold = mem;
system("date");
printf ("mark %d\n", mem);
}
else
{
if (mem > memold)
{
memold = mem;
system("date");
printf ("mark %d\n", mem);
}
}
}
pclose (pcmd);
sleep(2);
}
}
