Firebase Stream example crashes: Stack error

[karanmakharia]

I am trying to run FirebaseStream default example with no changes. But still the ESP8266 crashes with this code:

Exception (28):

I tried running esp exception decoder but it prompts me to select ELF file. I dont know where I can find ELF file.
ESP8266 board version: 2.2.3

@karanmakharia I had the same problem, this PR addresses this issue

@skhaz Thanks. It worked. But I am still not able to push data while the stream is on. Can you tell me how to do that.
