publish example throws LoadStoreAlignmentCause exception

[rpgit12]

Hi,

I've successfully got WiFi to work on an Feather Huzzah ESP8266, but am unable to get MQTT to work. The publish example consistently throws an LoadStoreAlignmentCause error.

The stacktrace is

Exception 9: LoadStoreAlignmentCause: Load or store to an unaligned address
PC: 0x4020269a: WiFiClient::WiFiClient() at ./Library/Arduino15/packages/esp8266/hardware/esp8266/3.0.1/cores/esp8266/Print.h line 46

Here's the console output, with debug for WIFI enabled. Any thoughts much appreciated!!!
