It is hard to follow what you are doing from the above code, however, you should not be calling "stop()" yourself. This is a function that is supposed to be internal to the API.
?
I see you are resetting your EReader object pointer in your code. Why? If the object is disconnected properly then this should not be required and the object can be directly reused.
?
Anyway, based on this error:
EReader::processMsgs (this=0x0) at IBUtilsCode/EReader.cpp (Segmentation Fault)
?
?
it looks like you are trying to de-reference the EReader object pointer when it has already been set to nullptr somewhere in your code.
