[ruby/prism] Handle zero-sized allocation in pm_constant_id_list_init_capacity 2025-02-13T20:12:43+00:00 HASUMI Hitoshi hasumikin@gmail.com 2025-02-01T05:49:33+00:00 31162bf4261b2e740f6e26f2c2f22c36d3556cf0 According to the calloc(3) man page, when nmemb or size is 0, `calloc()` can either return NULL or a unique pointer that can be passed to `free()`. While gcc and clang typically return a unique pointer, mruby's `mrb_calloc()` returns NULL in this case. Since `pm_constant_pool_init()` is commonly called with capacity=0 during normal operation of Prism, explicitly handle this case by setting `list->ids` to NULL when capacity is 0. This approach is portable across different calloc implementations and avoids potential issues with mruby's allocation behavior. This maintains compatibility with `free()` and `realloc()`, as passing NULL pointers to these functions is explicitly allowed by their specifications. https://github.com/ruby/prism/commit/1c32252df7
