On Cygwin, setrlimits cannot be used to set total memory availabe
for a process.
* test-suite/standalone/test-out-of-memory: skip for cygwin
* test-suite/standalone/test-stack-overflow: skip for cygwin
On Darwin, setrlimit is ignored, and these tests do not terminate. There
doesn't seem to be another way to limit the memory allocated by a
process.
* test-suite/standalone/test-stack-overflow: Skip this test on Darwin.
* test-suite/standalone/test-out-of-memory: Skip this test on Darwin.
* 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.
* libguile/throw.c (throw_without_pre_unwind): Newline after the
unwind-only warning.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-stack-overflow: New test to handle
mmap/malloc failure.
