Richard Quirk 68202d8ffb Extra check for auto_ptr new[] 
This fixes cases like this:

   auto_ptr<foo> bar(new foo[10]);

which previously did not work correctly.

Thomas Jarosch 43e9c1f0bd STL check: Detect return of implict string conversion + .c_str() 
Examples are:

or

    return ("ERROR: " + std::string("crash me")).c_str();

Daniel Marjamäki d23c58d387 enable: break out 'performance' and 'portability' from the 'style' id. Ticket: #3074 2011-09-03 15:30:30 +02:00
Kimmo Varis cfcfa3f000 Use "enabled" list for the style checking. 
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.

Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.

Pete Johns 098f0bf3e6 Fixed #2526 (Make TODO_ASSERT_EQUALS take three arguments (value, to_be, as_is)?... 
Removed replaced EXPECTED with...

WANTED (to-be):     The future expected value.
CURRENT (as-is):    Documenting how cppcheck behaves now.

This removes the need for an ASSERT_EQUALS but enforces the check for every TODO_ASSERT_EQUALS.
