File: backtrace
This bug happened in e2_setup_block_mode() on line epson2-ops.c:1218 (backend libraries) in the following code:
1207 if (s->hw->connection == SANE_EPSON_SCSI)
1208 maxreq = sanei_scsi_max_request_size;
1209 else if (s->hw->connection == SANE_EPSON_USB)
1210 maxreq = 128 * 1024;
1211 else
1212 maxreq = 32 * 1024;
1213
1214 /* XXX verify if this can b extended to other models */
1215 if (s->hw->connection == SANE_EPSON_NET && e2_model(s, "LP-A500"))
1216 maxreq = 64 * 1024;
1217
1218 s->lcount = maxreq / s->params.bytes_per_line;
1219
1220 DBG(1, "max req size: %d, line count: %d\n", maxreq, s->lcount);
1221
1222 /* XXX investigate this */
gdb shows the following content of s->params:
{format = SANE_FRAME_GRAY, last_frame = 1, bytes_per_line = 0,
pixels_per_line = 0, lines = -5, depth = 8}
so a division by zero may indeed be not looked favourably upon. maxreq was
set on lind 1210 as this is indeed SANE_EPSON_USB scanner.
The same crash, exactly, happened again and in the same circumstances, i.e. while attempting to adjust via GUI a rectangle to be scanned. So this is repeatable but I have no idea how to repeat that at will as after an xsane restart "the same" operation succeeded without any issues. Bug #667858 is the same issue on F-13. sane-backends-1.0.21-6.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/sane-backends-1.0.21-6.fc14 sane-backends-1.0.21-6.fc13 has been submitted as an update for Fedora 13. https://admin.fedoraproject.org/updates/sane-backends-1.0.21-6.fc13 sane-backends-1.0.21-6.fc13 has been pushed to the Fedora 13 testing repository.
