> Currently there is widespread use of assert in the thrift C++ runtime library.  Some of the more disturbing cases are security related, for example checking header sizes.  I recommend we eliminate assertions that are only checked in debug mode, and instead throw the appropriate exception, usually a TTransportException with CORRUPTED_DATA as the reason.  If we're going to check for an overflow or a buffer overrun, we should do so in debug and release modes.  Further, assertions are not easily tested whereas exceptions are.
