Well, if I change the cleanup code for usbDevs in sane_exit() from:
for( tmp = usbDevs; tmp; tmp = usbDevs->next ) {
free( usbDevs );
usbDevs = tmp;
}
to:
for( tmp = usbDevs; tmp; ) {
tmp = usbDevs->next;
free( usbDevs );
usbDevs = tmp;
}
It eliminates the double-free malloc error, so the backend runs
cleanly without the error.
However, instead of scanning the whole page I get just a small
corner. I wonder if endian issues are at play here with the image
size the scanner is told to scan?
