[New-bugs-announce] [issue39307] Memory leak in parsetok

[Alex Henrie]

New submission from Alex Henrie <alexhenrie24 at gmail.com>:

The parsetok function currently contains the following code:

    if (!growable_comment_array_init(&type_ignores, 10)) {
        err_ret->error = E_NOMEM;
        PyTokenizer_Free(tok);
        return NULL;
    }

    if ((ps = PyParser_New(g, start)) == NULL) {
        err_ret->error = E_NOMEM;
        PyTokenizer_Free(tok);
        return NULL;
    }

If PyParser_New fails, there is a memory leak because growable_comment_array_deallocate is not called on type_ignores.
