1.2       paf         2: 
1.3       paf         3: Parser in it's work with memory relies on garbage collection. See  http://www.hpl.hp.com/personal/Hans_Boehm/gc
1.2       paf         4: 
1.3       paf         5: Work with memory goes like this:
1.4     ! moko        6: all allocations are in the end get to pa_malloc pa_malloc_atomic, pa_realloc, pa_free functions;
        !             7: For C++ corresponding new operators are overloaded. To allocate a memory in C++ style one should specify,
        !             8: will the block contains pointers, use new when "it will" or new(PointerFreeGC) when "it will not".
1.2       paf         9: 
1.4     ! moko       10: For convinient memory allocation for objects there is root class PA_Object,
        !            11: overriding new operator and check usage for malloc/malloc_atomic/realloc/free.
1.3       paf        12: It is recommended, where it is possible, to allocate memory in C++ style [using new operator],
                     13: exception can be made for a case where realloc is needed:
                     14: on many platforms new-operator changes the pointer, returned by new-operator-implementation allocator.
                     15: that is new+realloc / realloc+delete are not allowed.
