#894: FreeBSD and MacOSX failures on 3.7.0 - group: geos::geom::CoordinateArraySequenceFactory, test: test<1> assertion failed ------------------------+--------------------------- Reporter: robe | Owner: geos-devel@… Type: defect | Status: new Priority: blocker | Milestone: 3.7.0 Component: Default | Version: master Severity: Unassigned | Resolution: Keywords: | ------------------------+---------------------------
Comment (by robe): More notes from gdt on mailing list https://lists.osgeo.org/pipermail/geos-devel/2018-August/008490.html {{{ I don't see this on NetBSD/7 amd64, which uses gcc 4.8. I did a build on macos 10.11, which uses clang (but a similar Intel processor): Apple LLVM version 8.0.0 (clang-800.0.42.1) Target: x86_64-apple-darwin15.6.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin and get the same failure as the bug. Specifically, if I run test 1 in that group, it fails: $ ./geos_unit geos::geom::CoordinateArraySequenceFactory 1 =============================== GEOS Test Suite Application =============================== geos::geom::CoordinateArraySequenceFactory: [1=F] ---> group: geos::geom::CoordinateArraySequenceFactory, test: test<1> problem: assertion failed tests summary: failures:1 ok:0 but tests 2,3,4,5 all pass. The test is in tests/unit/capi/GEOSGeomFromWKBTest.cpp in the sources, and is doing: // POINT(1.234 5.678) std::string wkt("POINT (1.234 5.678)"); std::string wkb("01010000005839B4C876BEF33F83C0CAA145B61640"); test_wkb(wkb, wkt); I don't know how to get it to produce the mismatching content; the --verbose option in --help is unrecognized, and I can't see how it would be reading the driver source. So I wonder if something in geos is sensitive to gcc/clang differences. (Vastly less likely, there could be a clang bug.) }}} -- Ticket URL: <https://trac.osgeo.org/geos/ticket/894#comment:6> GEOS <http://trac.osgeo.org/geos> GEOS (Geometry Engine - Open Source) is a C++ port of the Java Topology Suite (JTS).
