If alloca could be used to get arbitrary-sized buffer the bug would not exist. Another Y story https://fosdem.org/2016/schedule/event/ada_memory/ https://fosdem.org/2016/schedule/event/ada_memory/ points out that Ada does not have this limitation. There it is a job of the compiler to allocate bug chunks outside of the stack not to cause stack overflows. C really needs such API.
