Sometimes unit test for tree distance fail

[nicklas]

On my computer I get this result from ./cu_tester measures:

    FAILED -   tests -  13 passed,   1 failed,  14 total.
           - asserts - 288 passed,   1 failed, 289 total.


  1. cu_measures.c:413  - CU_ASSERT_EQUAL(tree_inter( "POLYGON((0 0, 3 1, 0 2, 3 3, 0 4, 3 5, 0 6, 5 6, 5 0, 0 0))", "GEOMETRYCOLLECTION(MULTILINESTRING((6 3, 8 4)),POINT(1 3.5))"),LW_FALSE)

It seems to pass on the tests on Debbie and others but not on my computer.

The problem is that DISTPTS is not initialized in lwtree.c function rect_leaf_node_intersects with lw_dist2d_distpts_init
