The backtrace cannot be given because it relies on the validity of the qstr data structures on the heap which may have been corrupted. In fact, it still can crash hard when the bytecode itself is overwritten. To fix, we'd need a way to skip gathering the backtrace completely. This also increases the default stack size on M4s so it can accomodate the stack needed by ASF4s nvm API.
