Knowing nothing about your code, I couldn't really suggest an
approach.  I don't even know whether fSenderReportBuffer is a field of
this, or a global variable, or what.  Could one of those identifiers
possibly be a reference created by dereferencing a bad pointer?  If
you disassemble the machine code at that line, does that help?

But please don't answer those questions.  :) Your post was closer to
being a request for help debugging your program than it was a question
about GDB per se, so it's a bit off-topic.  But if you have a question
specifically about GDB, please feel free to ask.
