Presuming that the bug has to do with the open/close allocation, that
sounds pretty reasonable to me.
Forgive me my confusion, but the following fragment here (I thought I
should try to reproduce your leak) doesn't appear to behave as I would
expect :
#include <netdb.h>
#include <stdio.h>
void main(void)
{
for (;;)
if (getservbyport(23, NULL) == NULL) {
fprintf(stderr, "argh!\n");
exit(1);
}
}
ie. it exits immediately. I tried various assortments of parameters
(eg. network and native order on the port, NULL, "tcp", "udp", etc for
the protocol). 8(
