[sane-devel] Segfault on Epson V850 epson2 driver

[Nicholas Andre]

Hey all,

Getting a segfault on epsonv2 when scanning at certain resolutions.
Scanning at 1800 DPI works fine but 2400 or 3200 triggers a segfault. This
is the dmesg output:

[328208.954596] usb 6-1: new high-speed USB device number 7 using xhci_hcd
[328209.108635] usb 6-1: New USB device found, idVendor=04b8,

Is there some documentation to compile a debug build and attach a debugger?

This happens when attempting to capture a 2400 dpi+ full 16 bit TPU8x10
scan.
