Interesting; the common occurrence of this did seem to be caused by memory exhaustion rather than the recursion, but perhaps that's a misdiagnosis or potentially another bug, unless excimer_log_find_or_add_frame is also pulling this data?

Worth noting that in contrast to the suspected cause in T342304#9119179, running it via php-cli here means the opcache is not enabled at all, so I don't believe this is from opcache corruption.
