Call to memset crashes my application in S130

I'm having the same issue in SDK 11. My code is the same as in examples/ble_peripheral/ble_app_uart/main.c

uint32_t               err_code;
ble_conn_params_init_t cp_init;
   
memset(&cp_init, 0, sizeof(cp_init));

Breaking at memset and issuing x cp_init yields Cannot access memory at address 0x20007fb0 Not sure what's going on here.

Unable to see this issue after N more attempts.

I agreed that it doesn't make any sense, that is why I posted this question...

I have just tried N more times and unable to reproduce it, probably it happens only with some preceding calls, I am closing this question for now, will open if I will see it again.

Ok. It doesn't make any sense that memset() crashes the application. What happens if you debug? Are you able to read the address of the variable? Could you please hand over you code? Then I could try to reproduce the issue.

Hi, no, I didn't figure that out.

Hi, did you manage to figure this out? memset() should not crash your application since the memory is already allocated in the preceding line.
