See #11151; this is still blocked by https://github.com/getsentry/symbolicator/issues/969#issuecomment-2033717006 -- note that that issue is closed but subsequent errors reported post-closure.

Moving to review in 18.0 cycle.

This means we don't get full line-level symbolication of call stacks, but we do get symbol names, so it's not completely the end of the world.

This is not yet fixed, see #11151.

https://github.com/getsentry/symbolicator/releases/tag/24.4.1 or https://github.com/getsentry/symbolicator/releases/tag/24.4.0 may have the support needed for this.
