Maybe the problems lies here (capture_opts.c) :
static gboolean capture_opts_output_to_pipe(const char *save_file, gboolean
*is_pipe)
{
int err;
if (save_file != NULL) {
/* We're writing to a capture file. */
if (strcmp(save_file, "-") == 0) {
/* Writing to stdout. */
/* XXX - should we check whether it's a pipe? It's arguably
silly to do "-w - >output_file" rather than "-w output_file",
but by not checking we might be violating the Principle Of
Least Astonishment. */
*is_pipe = TRUE;
} else {
/* not a capture file, test for a FIFO (aka named pipe) */
err = capture_opts_test_for_fifo(save_file);
switch (err) {
case ENOENT: /* it doesn't exist, so we'll be creating it,
and it won't be a FIFO */
case 0: /* found it, but it's not a FIFO */
break;
case ESPIPE: /* it is a FIFO */
*is_pipe = TRUE;
break;
default: /* couldn't stat it */
cmdarg_err("Error testing whether capture file is a pipe: %s",
strerror(errno));
return 2;
}
}
}
*is_pipe = FALSE;
return 0;
}
If you read this function, you can see that it can only set is_pipe to FALSE,
or raise an error.
The line " *is_pipe = FALSE;" should be at the beginning of the function,
not at the end.
At least for me, it fixed the problem described in bugs 1181 et 1220.
I created bug #1220 because, sorry, the keywords I used wehre not the right
ones.
I attached a patch to bug #1220, but nobody seems to have taken care of.
Hope it will close the issue for you also !

Pierre
