I am processing a bunch of RAW files I took for startrail imaging. I switched off the dark subtract of the camera (Panasonic G5) and recorded a separate dark frame, that I am subtracting with ufraw. I prepared a .ufraw file with neccessary settings and process using ufraw-batch --conf=example.ufraw.
This works fine for most images, but some (9 in 75) do crash ufraw in different ways: Most often I get an (*)
stack smashing detected : ufraw-batch terminated
======= Backtrace: =========
(*) followed by a longish memory map - attached
On two other occasions, it just died with a segfault, one other triggered the message 'Trace/breakpoint trap'
I had also tried saving as TIFF instead of JPEG, but got the same stack smashing crashes.
If I process the file without subtracting the dark things go fine.
If needed I can make a RAW/dark/ufraw file set available.
