#83048 I created a simple code that does nothing more that tries to print
__FILE__ __LINE__ and __func__ ( or __FUNCTION__) and the esp crashes at __func__.

I will like to use to use __func__ for debugging on a much bigger project, but I saw this crash and I tried to create this simple code to isolate the issue.

Searching on the internet reveals nothing.

I tested on more than 10 esp s , I got the same issue.
The wiring works fine, the voltage is ok, etc, I have a relatively big project that works fine with the same setup, but when I use __func__ it compiles, but it crashes.

If there a way to fix this ?


void setup() {
// put your setup code here, to run once:
