WINDOWS 7 PROFESSIONAL - 32 BIT (6.1 BUILD 7601 - SERVICE PACK 1)
CPU: INTEL CORE(TM)2 DUO CPU E7500 @2.93GHZ (2CPUs) - 64 BIT
GPU: ATI RADEON HD 3450 (DELL OPTIPLEX)
RAM: 4 GB

Krita 2.7.9.6 - 32 bit (installed today with the latest installer by Boud)

Reproducible: Always

Steps to Reproduce:
1. Fire up Krita 2.8 beta 2 (*32 bit*)
2. Open a jpg image (9 Mb around)
3. Filter > Adjust > Brightness - Contrast
4. Move the curve *quickly* until Krita always crashes.
Usually, it takes around 30-40 second to crash Krita

I have also tried this same workflow with the latest Krita 64 bit installer
It has been installed on Windows 7 - 64 bit (Intel I7 - Nvidia graphic card - 8 gb ram)
With these same steps (and the same jpg image) it is impossible for me to reproduce this crash
I have tried over and over but Krita on this 64 bit - Windows version never crashes.

Btw, I have tested all the previous 32 bit installers on Windows 7 (32 bit) and they always crashed with this filter (hence this crash is not a regression).
Actual Results:  
Krita 2.8 beta 2 always crashes on Windows 7 - 32 bit (with around 4 Gb Ram available) while trying the filter Brightness - contrast curve
On the contrary, Krita 2.8 beta 2 never crashes on Windows 7 - 64 bit (8 Gb Ram) with the same steps.

Expected Results:  
Krita 2.8 - 32 bit should not crash on Windows  7 (32 bit) with the filter brightness - contrast curve
It works fine on Windows 7 - 64 bit instead (8 gb ram) :-)
