System Workbench for STM32

I have the same problem. See attached file.

- The Hardware is STM32F405RG (olimex development board) connected with St-LinkV2
- The code is original generted from STM32CubeMX without any changes from my side.
- The Hardware is running without any problems with EmBiz
- the debugger stops in the first line of the main correctly. When continue for the next Braekpoint it stops with Sgint Interrupt anywhere in the program.
- It is a software problem may be the code from STM32CubeMX is incomplete, because I do not see any Interrupt handler in the code or there is a buck in the software from AC6.

Does anybody knows how to solve the problem
