Comment:

 I was able to replicate the crash on my PG 11 running below.

 {{{
 postgis_full_version
  POSTGIS="3.3.2 3.3.2" [EXTENSION] PGSQL="110" GEOS="3.11.1-CAPI-1.17.1"
 PROJ="7.2.1" LIBXML="2.9.9" LIBJSON="0.12" LIBPROTOBUF="1.2.1"
 WAGYU="0.5.0 (Internal)" |
 PostgreSQL 11.17, compiled by Visual C++ build 1914, 64-bit


 }}}
  P13, 15, and 16 appeared to be fine on the same windows server and
 version of PostGIS



 So appears to be something not specific to OS,  but possibly linked to
 PostgreSQL major version.  The difference might be specific to a major
 version in that maybe certain exceptions are better handled in newer
 PostgreSQL versions
