- Description updated (diff)
- Backport changed from 2.0.0: UNKNOWN, 2.1: UNKNOWN to 2.0.0: REQUIRED, 2.1: REQUIRED
Not only openssl.so, resolv.rb too.
The cause is exec_recursive
used by rb_hash_any
stores the current method name, but it isn't set in the required top-level, and a few other cases.
Updated by nobu (Nobuyoshi Nakada) almost 10 years ago
- Description updated (diff)
One of the simplest code to reproduce it is:
$ ruby -e '{["foo"]=>nil}; p Thread.current[:__recursive_key__]'

thread.c: get rid of invalid ID symbol
- eval.c (rb_frame_last_func): return the most recent frame method
name. - thread.c (recursive_list_access): use the last method name,
instead of the current method name which can be unset in some
cases, not to use a symbol by the invalid ID.
