The errors are varied and don't seem to apply to the change I made. Here's one:

I'm running on linux and I updated my toolchain and my esp-idf repo (and submodules). I've got an esp32 wroom dev board.
I stripped down the code and setup a conditional to select the two different ways of setting up the wifi so I could demonstrate the issue more clearly but just adding the curly braces caused the crash. This makes me suspect it's an issue with scope.
So here's my code. There is a compile time #define CRASH_LOOP. Enable this and the board will stop working.
