Is this a new problem with the mgos libraries?

as an aside one thing I noticed is that GPIO_PIN_X now need
#include “driver/gpio.h” but did not until recently

I noticed recently the core dumps after a sntp update with negative delta.
The origin seems to be in schedule_next_timer.

It occurs with mos latest. Building for 2.19.0 seems to be ok.

What is the result of mos debug-core-dump?

Thanks nliviu! I did not know about mos debug-core-dump. Sweet I will go back to 2.19.0. -Ted
