I don't understand how this could have happened. The only place that
sets abort_on_gc true is prin1-to-string, but it is not in the
backtrace. So somehow that setting was not reset at the end of
prin1-to-string, and it looks like the only way that could have
happened is if some code triggered by prin1-to-string set
throw-on-input or called while-no-input. Is this likely to have
happened during what you did?
Does anyone know/remember why we cannot allow GC during
prin1-to-string? I'm not sure I understand why we do that, and the
comments don't help.
