Good:
{{{
$ ./miniruby -e "@foo = 'hey'; ocid = @foo.object_id; @foo = 'ok';
1000.times { GC.start }; p ObjectSpace._id2ref(ocid)"
Segmentation fault
}}}
Not good:
{{{
$ ./miniruby -e "@foo = 'hey'; ocid = @foo.object_id; @foo = nil;
1000.times { GC.start }; p ObjectSpace._id2ref(ocid)"
"hey"
}}}
Re-assigning an instance variable (slot-based) using an immediate value
doesn't emit a GC write barrier, therefore the old variable leaks.
