Sorry.
Our module builds choke on merging several modules, containing
declarations from STL (we are using libc++, no modulemaps).
When writing a new module containing the definition of a STL
reverse_iterator, it collects all its template specializations. Some of
the specializations need to be deserialized from a third module. This
triggers an iterator invalidation bug because of the deserialization
happening when iterating the specializations container itself. This
happens only when the container's capacity is exceeded and the
relocation invalidates the iterators and at best causes a crash (see
valgrind reports in the bug report). Unfortunately I haven't been able
to make the reproducer independent on STL.

It might be handy to give an overview of the issue in the review (&
certainly in the commit) message rather than only citing the bug number
