Issue #20666 has been updated by ErezGeva2@gmail.com (Erez Geva). File small_ruby_test_log.zip added Did some minimising. # Three sources: ## `extconf.rb`
require 'mkmf' create_header create_makefile 'good' ## `good.cpp` #include <ruby.h> extern "C" void Init_good(void) {rb_require("bad");} ## `load.rb` begin require 'good' rescue LoadError => e print "#{e.to_s}\n" end
# Result on Linux `$ ruby extconf.rb; make; ruby -I. load.rb; echo $?`
creating extconf.h creating Makefile compiling good.cpp linking shared-object good.so cannot load such file -- bad 0
We catch the `LoadError` exception and exit gracefully. # Result on Windows Using the same Ruby 3.1.6 and Ruby 3.2.5 with GCC MinGW-W64 ucrt64 We run the same test in `small ruby test`. We get `Segmentation fault`. Attach is the log files of the `small ruby test`.
