flegita application just disappears when initializing scanner. This happens if media-gfx/gnome-scan-0.7.2 is built with the following CFLAGS: CFLAGS="-O2 -pipe -march=native" or even CFLAGS="-O2 -pipe -march=native -mno-avx" I mention -mno-avx since there are a number of bugs related to this: see Bug 357287 and Bug 352495. But works fine if built with CFLAGS="-O2 -pipe" Reproducible: Always Actual Results: $ flegita ** (flegita:20958): DEBUG: gnome-scan-init.vala:33: Initializing GNOME Scan 0.7.2 for flegita ** Message: gsane-module.c:54: SANE version is 1.0.21 for GSANE 0.7.2 ** (flegita:20958): DEBUG: gnome-scan-dialog.vala:400: job status updated to unconfigured ** (flegita:20958): DEBUG: gnome-scan-dialog.vala:400: job status updated to unconfigured ** (flegita:20958): DEBUG: gnome-scan-dialog.vala:400: job status updated to unconfigured ** (flegita:20958): DEBUG: gnome-scan-dialog.vala:400: job status updated to unconfigured ** (flegita:20958): DEBUG: Device Hewlett-Packard psc_1200_series (hpaio:/usb/psc_1200_series?serial=HU41GGQ0D55H) : 17 options ** (flegita:20958): DEBUG: Group "Scan mode" ** (flegita:20958): DEBUG: get mode(2) = 'Color' ** (flegita:20958): DEBUG: option 02 : mode = "Color" ; enum = {"Lineart", "Gray", "Color"} ** (flegita:20958): DEBUG: get resolution(3) = 75 ** (flegita:20958): DEBUG: option 03 : int resolution = 75, range = [75;1;600] ** (flegita:20958): DEBUG: Group "Advanced" ** (flegita:20958): DEBUG: get contrast(5) = 0 ** (flegita:20958): DEBUG: option 05 : int contrast = 0, range = [0;1;100] ** (flegita:20958): DEBUG: get compression(6) = 'JPEG' ** (flegita:20958): DEBUG: option 06 : compression = "JPEG" ; enum = {"None", "JPEG"} ** (flegita:20958): DEBUG: get jpeg-quality(7) = 10 ** (flegita:20958): DEBUG: option 07 : int jpeg-quality = 10, range = [0;1;100] ** (flegita:20958): DEBUG: get batch-scan(8) = 0 ** (flegita:20958): DEBUG: option 08 : boolean batch-scan = FALSE ** (flegita:20958): DEBUG: get source(9) = 'Flatbed' ** (flegita:20958): DEBUG: option 09 : source = "Flatbed", enum = {"Flatbed"} ** (flegita:20958): DEBUG: option 10 : Ignoring sensor (null) ** (flegita:20958): DEBUG: Group "Geometry" ** (flegita:20958): DEBUG: get length-measurement(12) = 'Padded' ** (flegita:20958): DEBUG: option 12 : length-measurement = "Padded" ; enum = {"Unknown", "Approximate", "Padded"} (and the application just vanishes)

The error happens with: CFLAGS="-O2 -pipe -march=core2" CXXFLAGS="${CFLAGS}" So I would say that the culprit is "-march=core2". I will attach a backtrace of the error.
Created attachment 281317 [details] backtrace of the error (with -march=core2)
