Comment (by strk):

 Merge request https://gitlab.com/postgis/postgis/-/merge_requests/58
 contains a partial change to avoid unaligned reads to at least the
 computed shortestLine. I think there are more possible unaligned reads BUT
 they could all be made against unserialized geoms which should be safe.

 Bas can you test that ?

 I wonder if we should provide alignment macros to ensure all our LWGEOMs
 are aligned no matter what... At least I say PostgreSQL source code making
 use of such macros for their code
