Valgrind reports memory leaks

[Pedro Lageira]

Hi Brad Hards,

thanks for your help. I have replaced the line:
gcry_control(GCRYCTL_DISABLE_SECMEM, 0);
with the line:
gcry_control(GCRYCTL_INIT_SECMEM, 1);

But Valgrind still reports a memory leak:
591 bytes definitely lost (instead of 1,081 bytes).
I'm sending the end of the Valgrind output in attach.

Thanks,

Pedro Lageira
