Incompatibility with ESP8266Audio

[probonopd]

There appears to be an incompatibility between https://github.com/electronicsguy/HTTPSRedirect.git#0415a49 and https://github.com/earlephilhower/ESP8266Audio.git#12131e9. As soon as I put rtttl = new AudioGeneratorRTTTL(); into my sketch anywhere (even after client->connect(host, 443);), making the connection fails in ~8 out of 10 tries.

My use case: I would like to fetch calendar events from a Google Scripts web app using HTTPSRedirect, and then play sounds using ESP8266Audio based on those events. Each library on its own works fine, but I never can get them to play nicely together.

What might be causing this incompatibility and how can it be solved?
