Out-of-memory issue when allocating a http request header buffer #6

Open TrainzLuvr opened 4 years ago

TrainzLuvr commented 4 years ago

Trying to setup a 512 byte buffer for reading the http request headers and failing to allocate it.

There could be an IDF setting that can be used to suppress the abort() call and instead just return nullptr.
