* test-suite/standalone/test-out-of-memory: * test-suite/standalone/test-stack-overflow: Compile these files before running them. That way, recursion can check the stack-overflow mechanism instead of the memory allocation mechanism. We compile beforehand as a prepass so as not to impose an rlimit on a Guile that previously ran auto-compilation.
