These have been around for a while, but shadowed by #21237. These need investigation as well.

It's tracer:

# tracer
Segmentation fault (core dumped)

tracer 1.2.1 is already in "updates", not only in "updates-testing". Just upgrading to it doesn't make it segfault. I'll figure out what else is needed.

@mvollmer interesting, tracer also crashes in #21309 . No idea at all if it's related, just making you aware.

Thanks. That looks different: it's not a segfault of the python process itself, but "just" a regular exception.
