Crash / segmentation faul when zooming in into one specific raw file

[abrock]

Short description

I have one Sony ARW file from a Alpha 7R II (I used APSC-crop) which triggers a segmentation fault.
It is reproducible every time in "Release" and "RelWithDebInfo" build mode but not "Debug" mode.
I tried to run RT with a debugger using QtCreator but it always stops with "SIGSTOP", not idea why.
Therefore I installed the RelWithDebInfo build, started RT and attached gdb.

Steps to reproduce

1. Put the file into a directory.
2. Switch to the directory and run "rawtherapee ."
3. Open the file
4. Zoom in using the mouse wheel
5. When the zoom hits 100% there is a segmentation fault

Expected behavior

Image visible 100%.

I'm, like OP, on Linux and Debian (10/Buster) and I'm not able to reproduce this either. Tried Official stable 5.8 appimage, the 5.8-2995 appimage and the latest development, self build, 5.8-3077.

I'm able to reproduce the bug, but only on this one machine, not on the other Debian testing machine.
The bug is reproducible without any pp3 file but I attached the one which is created.
