I don't know how to interpret _sbin_fsck.vfat.1000.crash.gz, so I can't confirm that the crashes that I saw are the same, but this patch resolves the few crashes that I saw with upstream dosfstools-2.11 due to zero slot numbers causing a negative offset in the call to copy_lfn_part in lfn_add_slot. On amd64 this results in a SIGSEGV in copy_lfn_part. On x86 the result is heap corruption and thus sometimes a SIGSEGV or double free abort later.
