For glibc Linux, there's also:

Is it possible to dynamically at run-time obtain a pointer to call

I'm particularly interested in a solution that'd work on 32-bit
Windows and on Dalvik. (On ART, desktop Linux, and 64-bit platforms we
can make the stack "large enough" anyway.)
Use case: Implementing a dynamic recursion limit.
