This destroyed the board I was working with. This should have failed with an error instead.

Hi @robbieh

Indeed, PlatformIO only prints a warning in case of a RAM overflow, but it shouldn't break your board. Could you please elaborate on what happened after you uploaded the binary?

The board stopped responding to attempts to program it over USB. I don't have a non-USB programmer handy, and I suspect using one would fix it.
