Hi!
In Cygwin terminal (bash) I typed:
cmp <(echo echo1) <(echo echo2)
This does not print anything.
Not even with -b.
On Linux (Ubuntu 12.04 in VMWare) it reports that the inputs are
different.
Bug?
Or am I missing something?

etc.
But only after I had modified cmp.c (diffutils) as follows:
int
main (int argc, char **argv)
{
...
#if 0
if (file_desc[f1] < 0 || fstat (file_desc[f1], stat_buf + f1) !=
0)
#else
if (file_desc[f1] < 0 || f1 ? ( stat (file[1], stat_buf + f1) != 0
)
: ( stat (file[0], stat_buf + f1) != 0
) ) // Henri: suspect fstat
#endif
{
if (file_desc[f1] < 0 && comparison_type == type_status)
exit (EXIT_TROUBLE);
else
error (EXIT_TROUBLE, errno, "%s", file[f1]);
}
}
/* If the files are links to the same inode and have the same file
position,
they are identical. */
if (0 < same_file (&stat_buf[0], &stat_buf[1])
&& same_file_attributes (&stat_buf[0], &stat_buf[1])
&& file_position (0) == file_position (1))
{ // Henri: diagnostics
#if 0
printf("same_file = %d\n", same_file (&stat_buf[0], &stat_buf[1]) );
printf("same_file_attributes = %d\n", same_file_attributes
(&stat_buf[0], &stat_buf[1]) );
printf("same file pos = %d\n", file_position (0) == file_position
(1) );
#endif
printf("file[0] = %s, file[1] = %s\n", file[0], file[1]);
printf("file_desc[0] = %d, file_desc[1] = %d\n", file_desc[0],
file_desc[1]);
printf("bailing out: same file.\n");
return EXIT_SUCCESS;
}
