Would it be possible for you to post your modified declaration of cfg_opt_t?
Thanks,
Keith

Hello,
I have add CFG_END at the end on my cfg_opt_t declaration, but I
have the same memory leek.
Regards,
Thomas

Thomas,
Actually you need to have CFG_END() at the end of your cfg_opt_t
declaration. That's how the cfg_init knows that it's at the end
of the opts[] array. See if that helps the memory leak that
you're encountering.

Hello,
I have made a simple application who use libconfuse (2.6) test.c:
##########################################
#include <confuse.h>
unsigned int test;
cfg_opt_t opts[] = {
CFG_SIMPLE_INT("test", &test)
};
cfg_t * cfg;
int main(void)
{
int err;
cfg = cfg_init(opts, 0);
err = cfg_parse(cfg, "test.conf");
if (err==CFG_FILE_ERROR)
printf("Error\n");
if (err==CFG_PARSE_ERROR)
printf("Parse Error");
cfg_free(cfg);
return 0;
}

I compile test.c
gcc test.c -lconfuse
I installed valgrind (
http://valgrind.org/)
When I launch my test application with valgrind :
valgrind --leak-check=full --show-reachable=yes a.out
I have this result :

libconfuse seems to not free a pointer allocated by cfg_yyalloc.
