Julia 1.10: segfault in jl_rettype_inferred

[kpamnany]

Opened for tracking. This crash happened intermittently on RAI's 1.10.2 (+various backports) build, after we loaded some package images containing only method specializations.

We have previously shared an rr trace and are working with @gbaraldi to find the problem.
