Issue #19584 has been updated by nobu (Nobuyoshi Nakada). Thanks. Since `Qnil` is never GC-ed, `rb_fs` and rgeo cases are OK. Other 3 cases are, even it would be very rare, can cause a crash. ---------------------------------------- Bug #19584: Crash in rb_gc_register_address https://bugs.ruby-lang.org/issues/19584#change-102694 * Author: peterzhu2118 (Peter Zhu) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- GitHub PR: https://github.com/ruby/ruby/pull/7670 Some C extensions pass a pointer to a global variable to rb_gc_register_address. However, if a GC is triggered inside of rb_gc_register_address, then the object could get swept since it does not exist on the stack. -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
