commit 4add825b2b0dc97dcbe24b48efa39f86d46d9599
Merge: bb4330e177 bfe56e94a2

    Merge pull request 'Initialize GSERIALIZED peek test fixtures on stable-3.3' (!611) from Komzpa/postgis:fix/gserialized-peek-valgrind-stable-3.3-20260728 into stable-3.3
    
    This backports the master fixture initialization from https://gitea.osgeo.org/postgis/postgis/pulls/569 to stable-3.3.
    
    The safety backport made the GSERIALIZED peek code validate payload bounds using the serialized size. The CUnit fixtures were manually allocated and then filled from the payload onward, leaving the header size and SRID bytes uninitialized. Valgrind therefore reported uninitialized reads in the unit test fixture even though the bounds-checking code is doing the right thing.
    
    The fix initializes the handcrafted GSERIALIZED header before writing the payload, matching master. The stable-3.3 NEWS entry cites GT-569, the master pull request number.
    
    Tested with `make -C liblwgeom check-unit CUNIT_WITH_VALGRIND=YES CUNIT_VALGRIND_FLAGS='--leak-check=full --error-exitcode=1'`.
