ruby-core #105103
Issue #18140 has been updated by stanhu (Stan Hu).
Thanks for the quick patch, Aaron! Thanks, Josh, for taking the initial repro step and boiling it down even further.
This explains why I didn't see the problem when I compiled Ruby with `-O0`.

Bug #18140: GC prematurely frees objects from implicit #to_ary conversion, leading to segfault
https://bugs.ruby-lang.org/issues/18140#change-93513
* Author: jhaberman (Josh Haberman)
* Status: Open
* Priority: Normal
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
The following repro crashes in every version of Ruby starting from 2.5.0 and including the latest (3.0.2):
```c
// test_ext.c
#include "ruby.h"
VALUE cFoo;
// Foo
typedef struct {
int dummy;
} Foo;
static void Foo_free(void* _self) {
fprintf(stderr, "Foo_free(%p)\n", _self);
xfree(_self);
}
static rb_data_type_t Foo_type = {
"Foo",
{NULL, Foo_free, NULL },
.flags = RUBY_TYPED_FREE_IMMEDIATELY,
};
static VALUE Foo_alloc(VALUE klass) {
Foo* _self = ALLOC(Foo);
fprintf(stderr, "Foo_alloc(%p)\n", _self);
return TypedData_Wrap_Struct(klass, &Foo_type, _self);
}
// Bar
typedef struct {
int dummy;
} Bar;
static void Bar_free(void* _self) {
fprintf(stderr, "Bar_free(%p)\n", _self);
xfree(_self);
}
static rb_data_type_t Bar_type = {
"Bar",
{NULL, Bar_free, NULL },
.flags = RUBY_TYPED_FREE_IMMEDIATELY,
};
static VALUE Bar_alloc(VALUE klass) {
Bar* bar = ALLOC(Bar);
return TypedData_Wrap_Struct(klass, &Bar_type, bar);
}
VALUE Bar_to_ary(VALUE _self) {
fprintf(stderr, "Bar_to_ary() begin\n");
VALUE ary = rb_ary_new2(2);
rb_ary_push(ary, Foo_alloc(cFoo));
rb_ary_push(ary, Foo_alloc(cFoo));
rb_ary_push(ary, Foo_alloc(cFoo));
fprintf(stderr, "Bar_to_ary() end\n");
return ary;
}
void Init_test_ext() {
cFoo = rb_define_class("Foo", rb_cObject);
rb_gc_register_address(&cFoo);
rb_define_alloc_func(cFoo, Foo_alloc);
VALUE bar = rb_define_class("Bar", rb_cObject);
rb_define_alloc_func(bar, Bar_alloc);
rb_define_method(bar, "to_ary", Bar_to_ary, 0);
}
```
```
#!/usr/bin/ruby
require 'mkmf'
$objs = ["test_ext.o"]
create_makefile("test_ext")
```
```
// test.rb
require "test_ext"
GC.stress = true
arr = [nil]
STDERR.puts("Bar.new")
bar = Bar.new
STDERR.puts("concat")
arr.concat(bar)
STDERR.puts("concat done")
```
Output is:
```
Bar.new
