  1. Allow Lint to see that constructor takes ownership of memory.

    Lint sees that ownership of allocated memory is taken by a constructor if the owning object isn't "new'd". But if the owning object is "new'd", then Lint does not understand this. See the example below, which works in the online demo.

    This was discussed in this thread, as well as several others:
    http://www.gimpel.com/Discussion.cfm?ThreadID=808

    //lint -e438, -e529, -e1502, -e1712, -e1788, -e714

    include <memory>

    struct A { A(char ){}; };
    void g( )
    {
    // This results in a 429 warning.
    char * ptr1 = (char
    ) malloc(10);
    A *a1 = new A(ptr1);

    // This does not result in a 429 warning. …

  2. Detect -e Options and -save without -restore

    -e Options without surrounding -save/-restore in the same file shall be warned.
    Also a -save without -restore in the same file or same block level shall be warned.

    In PC-lint Plus, suppression options inside a source module do not “leak” to subsequent modules so this is less of an issue for PC-lint Plus than it was for PC-lint but we do plan to add a warning for -save options that do not have corresponding -restore options in a future update to PC-lint Plus.

  3. Use a fixed release cycle

    Customers could plan better, if they knew you have 2 or 4 releases per year.
    Right now it´s totally unpredictable.

  4. Display all options currently in effect (What Options am I using here)

    Although "-vo" and "lint usual arguments ?" are useful, they produce a lot of information, including information that sometimes could be considered 'what was noise' such as temporary error suppressions "-save, -e123, -restore"

    It would be great if you could add a feature where I could display all options, suppressions, flags, etc. in effect at a specific point in a source file that have been:
    a) changed from the defaults, or
    b) changed since the last "-save"
    c) changed in this file

    for example:

    //lint -save
    
    //lint -e123
    //lint -esym(456, FooBar)
    ...
    /*lint -save -e789 */ MACRO /*lint -restore */

  5. Out Of Bounds Checking at Start Of Array

    This is 'out-of-bounds' is detected:

    unsigned char buffer[5];
    unsigned char* buffer_ptr = &buffer[4];

    ++bufferptr; // ERROR! now points to 1 byte after &buffer[4]
    *buffer
    ptr = 0x12; // assign to memory outside of buffer[]

    This 'out-of-bounds' is NOT detected:

    unsigned char buffer[5];
    unsigned char* buffer_ptr = &buffer[0];

    --bufferptr; // ERROR! now points to 1 byte before &buffer[0]
    *buffer
    ptr = 0x12; // assign to memory outside of buffer[]

    As 'buffer_ptr' has been 'bound' to 'buffer' via the assignment I would have expected PC-lint to have detected this.
