Adding the code below to src/test/common/test_tableformatter.cc dumps core upon flush().

TEST(tableformatter, singlecolumn)
{
  std::stringstream sout;
  TableFormatter formatter;
  formatter.dump_int("int", 1);
  formatter.dump_int("int", 2);
  formatter.flush(sout);

  std::string cmp = "" 
  "+------+\n" 
  "| int  |\n" 
  "+------+\n" 
  "| 1    |\n" 
  "+------+\n" 
  "| 2    |\n" 
  "+------+\n";
  EXPECT_EQ(cmp, sout.str());
}
