the epson.c has a bug (his come up only for the scsi scanners):
Into scsi_write :
-------
static int
scsi_write (int fd, const void *buf, size_t buf_size, SANE_Status *
status)
{
unsigned char *cmd;
[...]
cmd = alloca (6 + buf_size);
[...]
if (SANE_STATUS_GOOD == (*status = sanei_scsi_cmd (fd, cmd1,
sizeof(cmd) +buf_size, NULL, NULL)))
--------
Obviusly sizeof(cmd) is wrong, should be:
if (SANE_STATUS_GOOD == (*status = sanei_scsi_cmd (fd, cmd1,
6+buf_size, NULL, NULL)))
btw there are some other bugs into epson.c (at least for scsi
scanners), and xscanimage quit when previewing an image.
bye,
Alex
