V565 An empty exception handler. Silent suppression of exceptions can hide the presence of bugs in source code during testing. test ttextinput.cpp 495


void testTextInput() {
  ...
  try {
    t.readNumber();
    alwaysAssertM(false, "Incorrect parse");
  } catch (....) {
  }
  ...
}

alwaysAssertM is written in a wrong place. The string with alwaysAssertM should be inside catch.
