- Mon May 27, 2019 2:14 am #82495 I'm trying to debug a large sketch, I'm occasionally getting a crash related to the web interface, and am trying to find out where exactly this is going wrong.

The stack trace ends with:

Code: Select all    last failed alloc call: 4022D552(1480)

This particular address is not present in the decode stack trace itself, but may hold the key to finding the source of the problem. Any suggestions on how to track this one down?

Code: Select all Decoding 36 results
