[Patch] Segfault on unaligned lseek() on /dev/sdX (was: [ITP] ddrescue 1.3)
Fri May 18 19:02:00 GMT 2007
Cygwin 1.5.24-2 segfaults on unaligned lseek() on raw block devices with
sector size >512 bytes.
$ dd skip=1000 bs=2047 if=/dev/scd0 of=/dev/null
$ ddrescue -c 1 /dev/scd0 file.iso
This is due to a fixed 512 byte buffer in fhandler_dev_floppy::lseek().
It is still present in HEAD revision.
The attached patch should fix. It should work for any sector size.
(Smoke-)tested with 1.5.24-2 (too busy to test with current CVS, sorry).

unaligned seek due to fixed size buffer.
