    88 What is strange are the sizes of LWGEOM vs LWPOINT reported (24 vs 32). Is there a problem with the alignment ? Is this a consequence of Ubuntu 20.04?
     159
     160The problem are the sizes of LWGEOM vs LWPOINT reported at the beginning (both 32) and after (24 vs 32). Therefore, the definitions of liblwgeom.h from 2.5.5 that are still in my system at /usr/local/include from the previous installation from PostGIS 2.5.5
     161{{{
     162/* POINTYPE */
     163typedef struct
     164{
     165        uint8_t type; /* POINTTYPE */
     166        uint8_t flags;
     167        GBOX *bbox;
     168        int32_t srid;
     169        POINTARRAY *point;  /* hide 2d/3d (this will be an array of 1 point) */
     170}
     171LWPOINT; /* "light-weight point" */
     172}}}
     173are conflicting with the new ones from PostGIS 3.1.3
     174{{{
     175/* POINTYPE */
     176typedef struct
     177{
     178        GBOX *bbox;
     179        POINTARRAY *point;  /* hide 2d/3d (this will be an array of 1 point) */
     180        int32_t srid;
     181        lwflags_t flags;
     182        uint8_t type; /* POINTTYPE */
     183        char pad[1]; /* Padding to 24 bytes (unused) */
     184}
     185LWPOINT; /* "light-weight point" */
     186}}}
     187Maybe the installation for PostGIS 3.x should remove the old versions 2.5.x installed in the system.
