Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- See Also| |https://gcc.gnu.org/bugzill | |a/show_bug.cgi?id=91582 --- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> --- The solution I'm working on for pr91582 adds tracking of dynamically allocated objects to the strlen pass (including alloca, VLAs, and user-defined allocation functions declared with attribute alloc_size). A natural extension of the project is to detect accesses to deallocated objects. A new function attribute such as "free" to parallel attributes malloc and alloca_size will be required to detect such deallocation by user-defined functions (the attribute will need to apply to specific function arguments to make it possible to use it with functions taking two more pointers). I expect to submit my patch for pr91582 in time for GCC 10 but the new attribute will most likely have to wait until GCC 11.
