- Sun Nov 15, 2015 5:58 am #34049 I've written a couple of C++ source files and I'm having issues with memory getting overwritten.

Is it possible that the 80K are full, and that stack and heap are touching each other ? How can I detect that ?

No it wasn't full. Some of my class instances were getting deallocated (their DTOR was called) so pointers to stuff coming from there were obviously invalid.

ESP.getFreeHeap() reports the amount of heap still available, currently around 28K for me.
