When a table is mutable, the LLVM backend fails to generate the correct code. The base and length of the table are cached at function start, meaning updates to the table won't be picked up by the function itself. This breaks calling dlsym and immediately calling the resulting function, and can potentially lead to a segfault if the table's elements are moved in memory.
