Exception 29

[sajeeshkv]

I have used the latest version v4.4.5. I have tried to use the subscribeTopic example in messaging folder. Code has compiled and uploaded successfully. The ESP8266 is restarting with Exception 29. I have tried to decode the error message using ESP Exception Decoder. The output of the exception decoder is given below. Kindly help to rectify the bug.

Exception (29):
epc1=0x4020c95d epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000134 depc=0x00000000
