Crash using curves

[Beep6581]

Originally reported on Google Code with ID 2820

I was trying to adjust the histogram and raw therapee crashed after adding three points.

I have been able to find a way to reproduce the problem, sometimes it crashes soon,
other times after adding a lot of points, anyway i think there is a bug somewhere.

I attach the image used, the profile used and a video showing how to trigger the bug
(i had to add a lot of points, i know in the video it's really forced but the first
time i found the problem it happened only with 3 points and in a normal way).

Thank you in advance.

Hey

I could not reproduce the crash in Linux using 4.2.235

Could you try 4.2.235, and if you can reproduce it there, can you provide a stack bactrace?

With debug version i've been unable to reproduce the crash.

With 4.2.235 non debug here is what gdb tells:

Can't reproduce, likely fixed recently by Ingo.
