That's the V3 MQTT code subscribing to the topics after connection has 
been established. The crash seems to have then been in the mongoose 
strdup() implementation, which again may point to some memory issue, but 
not of the type I observed (i.e. no heap corruption involved directly).

If that repeats, I suggest trying with v3 server disabled.

Regards,
Michael
