[sane-devel] Segmentation fault with Airscan

[Yoann Le Montagner]

Hi,

I encounter a segmentation fault when trying to use my scanner Canon 
Pixma TS8350. Xsane crashes, and 'scanimage -L' shows a segmentation 
fault that seems to be issued by Airscan:

yoann at yoann-desktop:~$ scanimage -L
Erreur de segmentation (core dumped)

I attach the output of 'SANE_DEBUG_DLL=255 scanimage -L' (file 
out_debug_all.txt) and 'SANE_DEBUG_AIRSCAN=1 scanimage -L' (file 
out_debug_airscan.txt).

Airscan version is 0.99.18+77.1, and sane-backends version is 
1.0.31-175-g016271ebd.

If I uninstall Airscan, the segmentation fault does not appear anymore, 
and I'm able to use the scanner. Still, it used to work with Airscan 
(with a previous version), as discussed two weeks ago on this list.

Regards,

Yoann
