Hi, do you mean the M8 images?
I can upload to Dropbox one stacked images (87MB) that cause the crash and post the link or all the dark and light frames (about 350MB).
I'm using only light and dark images captured using a DSLR Canon EOS 50D.
The steps I followed are:
- Convert 7 CR2 dark frames to FIT, no demoisaicing, keep 3 channels
- Create master dark using average with rejection, no normalisation, Winsorized sigma clipping (set to get rejection values about 0.5)
- Convert 10 CR2 light frames to FIT, no demoisaicing, keep 3 channels
- Calibration of the light images using master dark, CFA checked, sigma parameters as default, resulting in 245 cold pixels and 45910 hot pixels (no red text)
- Creation of sequence using the calibrated ligth frames, demosaicing checked, keep 3 channels.
- Registration of the light frames using default values and Global Star Alignment, Bicubic algorithm.
- Selection of a reference image.
- Stacking of the light frames using average with rejection, Aditive Scaling normalisation, Winsorized sigma clipping (set to get rejection values about 0.5)
At this point I get a stacked image, looks good, good signal-noise ratio at eye.
Next step I take is Color Calibration, selecting a background area in the image and clicking on "Use current selection" and "Background neutralization". After clicking Background neutralization, Siril crashes. The error output in terminal begins with
*** Error in `siril': double free or corruption (!prev): 0x00000000034de670 ***
followed by a backtrace and a memory map list, ending with the dump core line:
I can provide a log for the stacking and color calibration steps; unfortunately, I have not been able to redirect all the terminal output to a file, so I took screenshots of the backtrace and memory maps.
I hope this helps. If you need the images, let me know and I will post a link to them.
