[ruby-core:120031] [Ruby master Bug#20915] Segfault with `TracePoint#parameters` and aliased C method
Issue #20915 has been reported by viralpraxis (Iaroslav Kurbatov). ---------------------------------------- Bug #20915: Segfault with `TracePoint#parameters` and aliased C method https://bugs.ruby-lang.org/issues/20915 * Author: viralpraxis (Iaroslav Kurbatov) * Status: Open * ruby -v: 3.3.6 * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I'm getting a segfault in the following example ```ruby C = Class.new do alias_method :new_to_s, :to_s end TracePoint.new(:c_call, &:parameters).enable { C.new.new_to_s } ``` Ruby: `MRI 3.3.6`, also `ruby 3.4.0dev (2024-11-27T19:36:50Z master 7dd2afbe3a) +PRISM [x86_64-linux]` The root cause of the issue lies in the `rb_tracearg_parameters` function within the `RUBY_EVENT_C_RETURN` branch. It seems like if invoked method is aliased to C function `rb_method_entry_without_refinements(..., trace_arg->called_id, ...)`. Specifically, when the invoked method is an alias for a C function, `rb_method_entry_without_refinements(..., trace_arg->called_id, ...)` may return NULL. In that case we can fallback to `trace_arg->id`.

Some additional context: before https://github.com/ruby/ruby/commit/837ef8911c638c3e2bdb6af710de7c1fac7b5f90 this code path used single `trace_arg->id` lookup, and the commit changed it to `trace_arg->called_id`. So we have to make both lookups to handle all edge cases.
