Do you think it is good to go now?
With kind regards,

Good catch, thank you!
Indeed, if we don't reset localifsSize then we could end up accessing
already freed memory, which is worse than just a memory leak.
Here's the updated webrev:

Hi Ivan,
Shouldn't you reset localifsSize to 0 in case of the early
return ? The comment says localifsSize is the size of the array so
the size of the array is 0 again after freeing.
637 static struct localinterface *localifs = 0;
638 static int localifsSize = 0; /* size of array */
639 static int nifs = 0; /* number of entries used in
array */
...
679 if (localifsTemp == 0) {
680 free(localifs);
681 localifs = 0;
682 nifs = 0;
683 fclose(f);
684 return;
685 }
Best regards, Matthias

Hello!
This seems to be the last use of realloc() without proper handling of a
failure.
Would you please help review a trivial fix?
