This test fails on all esp32 boards without this fix, because the try/except that runs with the heap locked attempts to increase the size of the globals dict when assigning to the exception variable `e`. Fix that by preallocating the global variable `e`. Signed-off-by: Damien George <damien@micropython.org>
