Failing to execute new Arduino Sketch

[themindfactory]

I have written a fairly complicated sketch and it was working just fine.... now it does not even get to setup()....

I get to https://github.com/espressif/esp-idf/bl ... t_access.c line 187 which asserts()

What can cause this??

It's failed to create the "dport access" worker task. Probably this is because of an out of memory error. Try modifying your sketch to allocate less static RAM.

The heap normally just prior to calling setup() or at least at the top of setup() is 110KBytes, this is enough? I would hope so....
