Comment (by robe):

 apologies that thing I thought was a failure

 is expected result and shows on stable-3.4 as well

 {{{
  Test: test_lwgeom_segmentize2d ...NOTICE:
 /builds/postgis/postgis/liblwgeom/ptarray.c:449 - ptarray_segmentize2d:
 Too many segments required (1.000000e+101)
 }}}

 But interestingly stable-3.4 32-bit gitlab run is not showing the
 test_grid_in_place error.
 That is passing with flying colors as is the rest of the tests

 https://gitlab.com/postgis/postgis/-/jobs/6398823690#L733

 I thought maybe it was the debian version, but master and stable-3.4 are
 running debian bookworm

 But I do notice the cu_misc.c grid tests change in master which I presume
 pramsey added to exercise
 what is causing the postgresql failures.

 master has an extra test:


 {{{
         do_grid_test(
                 "LINESTRING(0 0,1 1,1 1,1 1)",
                 "LINESTRING(0 0,1 1)",
                 0.001
         );
 }}}
 I'm going to add this to 3.4 as well to see if gitlab test32 is still a
 happy camper.
