When a pp3 contains negative values for X & Y in the Crop section these get parsed into array indexing code without being checked and set to 0. This results in a segmentation fault because the code tries to index the '-1' element of the array.
RawTherapee is a powerful, cross-platform raw photo processing program, released under the GNU General Public License Version 3. It is written in C++ using a GTK+ front-end and a patched version of dcraw for reading raw files. It is notable for the advanced control it gives the user over the demosaicing and developing process.
