bug#32604: 26.1.50; memory leak in connect_network_socket


From: YAMAMOTO Mitsuharu
Subject: bug#32604: 26.1.50; memory leak in connect_network_socket
Date: Sat, 1 Sep 2018 14:38:51 +0900

In connect_network_socket (in process.c), the memory pointed to
by the variable `sa’ doesn’t seem to be deallocated.

  3328    struct sockaddr *sa = NULL;
        :
  3347    while (!NILP (addrinfos))
  3348      {
        :
  3359        if (sa)
  3360          free (sa);
  3361        sa = xmalloc (addrlen);
        :
  3533      }
        :

The following patch would fix the leak:

diff --git a/src/process.c b/src/process.c
index 676f38446e..e5b70ca058 100644
--- a/src/process.c
+++ b/src/process.c

 #endif
     }
 
+  xfree (sa);
+
   if (s < 0)
     {
       const char *err = (p->is_server


Also, line 3359-3361 above could be:
      sa = xrealloc (addrlen);
