ObjectSpace.trace_object_allocations_start could crash since it adds a TracePoint for when objects are freed. However, TracePoint could crash since it modifies st tables while inside the GC that is trying to free the object. This could cause a memory allocation to happen which would crash if it triggers another GC.

Fix crash in tracing object allocations
ObjectSpace.trace_object_allocations_start could crash since it adds a
TracePoint for when objects are freed. However, TracePoint could crash
since it modifies st tables while inside the GC that is trying to free
the object. This could cause a memory allocation to happen which would
crash if it triggers another GC.
