server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
connection to server was lost

when I run this on my system I don't get a crash though, I get

NOTICE:  Coordinate values were coerced into range [-180 -90, 180 90] for GEOGRAPHY

ERROR:  Cannot find SRID (-2146484647) in spatial_ref_sys
CONTEXT:  SQL function "st_intersection" statement 1
SQL state: XX000

So crash I guess might be ARM specific, though having a crazy srid is not that helpful either.

Looks like it's the _ST_BestSRID function coming up with that SRID

 SELECT _ST_BestSRID('0102000020E610000005000000000000000000F07F000000000000F07F000000000000F07F000000000000F07F000000000000F07F000000000000F07F000000000000F07F000000000000F07F000000000000F07F000000000000F07F'::geometry, '0101000020E6100000000000000000F07F000000000000F07F'::geometry)

Yields: -2146484647

In 2c76ff2/git:

Reject infinite coordinates in _ST_BestSRID

to prevent crash on ARM (maybe other systems too)
References #5347 for PostGIS 3.4.0

Also change convert to gserialized logic to use newer syntax

Your fix works for me on Apple ARM. No crash, proper errors generated.
