Different hard faults on STM32H562

[lors]

I have a problem here:
When calling strcat() on a target string with odd length and odd source, the controller goes into hardfault, SCB_UFST_UNALIGNED is set. 

If I deactivate the unaligned trap (SCB_CCR_UNALIGN_TRP == 0), the following happens.

The controller goes into hardfault on calling putchar(), SCB_BFSR_IBUSERR set. Many previous calls to putchar() work fine.

I use CUBEide with GNU Tools for STM32 12.3rel1.
The code has already been compiled for other STM32 derivatives and other versions of GNU Tools, and works fine on these systems.

The Problem is solved.
