Previously 'load-thunk-from-memory' would often throw to 'system-error' when passed an incorrect ELF file, leading to incorrect error messages. * libguile/loader.c (load_thunk_from_memory): Reset 'errno' when 'check_elf_header' returns non-NULL. * test-suite/tests/vm.test: New file. * test-suite/Makefile.am (SCM_TESTS): Add it.
