* libguile/gc.c (scm_oom_fn, scm_init_gc): Install an out-of-memory handler that raises an unwind-only out-of-memory exception. (scm_gc_warn_proc, scm_init_gc): Install a warning proc that tries to print to the current warning port, if the current warning port is a file port. (scm_gc_after_nonlocal_exit): New interface. Should be called after a nonlocal return to potentially collect memory; otherwise allocations could try to expand again when they should collect. * libguile/continuations.c (scm_i_make_continuation): * libguile/eval.c (eval): * libguile/throw.c (catch): * libguile/vm.c (scm_call_n): Call scm_gc_after_nonlocal_exit after nonlocal returns. * libguile/throw.c (abort_to_prompt, throw_without_pre_unwind): Rework to avoid allocating memory. (scm_report_out_of_memory): New interface. (scm_init_throw): Pre-allocate the arguments for stack-overflow and out-of-memory errors. * module/ice-9/boot-9.scm: Add an out-of-memory exception printer. * module/system/repl/error-handling.scm (call-with-error-handling): Add out-of-memory to the report-keys set. * libguile/gc-malloc.c (scm_realloc): Call scm_report_out_of_memory if realloc fails. * libguile/error.h: * libguile/error.c: * libguile/deprecated.h: * libguile/deprecated.c (scm_memory_error): Deprecate. * test-suite/standalone/Makefile.am: * test-suite/standalone/test-out-of-memory: New test case.
