Description
Hi, libffi-3.4.2 recently landed in Fedora and since that time, I observe strange failures in Ruby test suite:
1) Failure:

ruby -v: ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [x86_64-linux]
make: *** [uncommon.mk:822: yes-test-all] Aborted (core dumped)
Executing the test on itself, they passes just fine, but testing e.g. test/ruby/test_autoload.rb -v -n '/TestAutoload#test_autoload_fork/' together with test/fiddle/test_import.rb makes the reproducer smaller.
Trying to reduce the issue even further, I have reduced the test/ruby/test_import.rb into the following shape:
# coding: US-ASCII
# frozen_string_literal: true
begin
require_relative 'helper'
require 'fiddle/import'
rescue LoadError
end
module Fiddle
module LIBC
extend Importer
dlload LIBC_SO, LIBM_SO
CallCallback = bind("void call_callback(void*, void*)"){ | ptr1, ptr2|
# f = Function.new(ptr1.to_i, [TYPE_VOIDP], TYPE_VOID)
# f.call(ptr2)
}
end
end if defined?(Fiddle)
And use just miniruby:
$ gdb --args ./miniruby -I./lib -I. -I.ext/common ./tool/runruby.rb --extout=.ext -- --disable-gems "./test/runner.rb" --ruby="./miniruby -I./lib -I. -I.ext/common ./tool/runruby.rb --extout=.ext -- --disable-gems" --excludes-dir=./test/excludes --name='!/memory_leak/' test/fiddle/test_import.rb test/ruby/test_autoload.rb -v -n '/TestAutoload#test_autoload_fork/'
