      When initiating the replica set from the driver one of the three members of the set will always crash with the following stack trace (built with --d):

      This does NOT happen locally on Mac OS X when using the binary or building from source but does happen using on Amazon Linux on EC2 using master or a binary.

      I tried to reproduce on a single mongod by writing a program which runs the {{

      {getnonce: 1}

      }} many times but I was unable to crash mongod in that way.

      Running addr2line on the stack trace built with --d yields line 130 in src/mongo/platform/random.cpp as the source:

      int64_t nextInt64() {  
  int64_t r;                                                                                                                 
  _in->read( reinterpret_cast<char*>( &r ), sizeof(r) );    
  if ( _in->fail() ) { 
    abort();
  }
  return r;
}
