[postgis-devel] test failure on WKT parser rebuild

[Sandro Santilli]

I'm getting weird (unstable) failures on rebuilding the WKT parser.
Under liblwgeom:

 Run Summary:    Type  Total    Ran Passed Failed Inactive
               suites     32     32    n/a      0        0
                tests    214    214    213      1        0
              asserts   1901   1901   1900      1      n/a

Under liblwgeom/cunit:

 $ ./cu_tester  | grep FAILED
 Test: test_wkt_in_errlocation ...FAILED

 $ ./cu_tester test_wkt_in_errlocation
 Running test 'test_wkt_in_errlocation' in suite 'in_wkt'.
    PASSED - asserts -   2 passed,   0 failed,   2 total.

 $ ./cu_tester in_wkt
 Running all tests in suite 'in_wkt'.
    FAILED -   tests -  14 passed,   1 failed,  15 total.
           - asserts -  73 passed,   1 failed,  74 total.
    1. cu_in_wkt.c:341  - fabs(12 - p.errlocation) < 1.5

It is weird that running the specific failing test does not
give a failure, while running it in it's enterety does.
Valgrind doesn't report any error.
The problem does not occur with the parser included in the
repository.

I'm using bison (GNU Bison) 3.0.2 and flex 2.5.35.

Can anyone reproduce the problem ?

PS: you rebuild the parsers with "make parser" under liblwgeom/ dir.
