Uh oh!
There was an error while loading. Please reload this page.
The make_gen() function creates and tracks generator/coro objects, but
doesn't fully initialize all the fields. At a minimum, we need to
initialize all the fields that may be accessed by gen_traverse because
the call to compute_cr_origin() can trigger a GC.
(cherry picked from commit 574405c)
