Raster unit tests failing with GDAL master

[Algunenano]

I'm using both GDAL and PROJ master.

Running test 'test_raster_compute_skewed_raster' in suite 'raster_misc'.

    FAILED - asserts -   4 passed,   1 failed,   5 total.


  1. cu_raster_misc.c:199  - CU_ASSERT_EQUAL(rt_raster_get_width(rast),2)

199             CU_ASSERT_EQUAL(rt_raster_get_width(rast), 2);
(gdb) p rast
$1 = (rt_raster) 0x555555799b70
(gdb) p *rast
$2 = {size = 0, version = 0, numBands = 0, scaleX = 1, scaleY = -1, ipX = -0.5, ipY = 0, skewX = 0.25, skewY = 0.25, srid = 0, width = 3, 
  height = 3, bands = 0x0}
(gdb) quit

This works fine with PROJ 5.2 and GDAL 2.3.2 in the same environment.

This now works fine with current master and also with gdal 3.0.0 + PROJ 6.1.0

Travis does not confirm either.

I've rebuilt with gdal release/3.0 and I reproduce it again:

  Test: test_raster_compute_skewed_raster ...FAILED
    1. cu_raster_misc.c:199  - CU_ASSERT_EQUAL(rt_raster_get_width(rast),2)

Using:

• Gdal release/3.0 currently at ​https://github.com/OSGeo/gdal/commit/eeff82f5a22d1816ff6882b9c0710195d0b7fc41.
• PROJ 6.1.0 (not sure if it matters)
• Postgis trunk, currently at ​https://github.com/postgis/postgis/commit/7bab445476440f30c9a06996a9bd4d3c762e790e

I have a feeling that this might depend on GDAL compilation options (CFLAGS / CXXFLAGS) since I couldn't reproduce it with the distribution packages but I do when building the package myself.

  C compiler:                gcc -DHAVE_AVX_AT_COMPILE_TIME -DHAVE_SSSE3_AT_COMPILE_TIME -march=native -mtune=native -O3 -pipe -fno-plt -Wall -Wextra -Wno-unused-parameter -g3 -gdwarf-4 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer
  C++ compiler:              g++ -DHAVE_AVX_AT_COMPILE_TIME -DHAVE_SSSE3_AT_COMPILE_TIME -march=native -mtune=native -O3 -pipe -fno-plt -Wall -Wextra -Wno-unused-parameter -g3 -gdwarf-4 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer

Same issue when building with gdal master (d029a90b04) - ​https://github.com/OSGeo/gdal/commit/d029a90b04037cd426dbc1b27e3f28225ed38c80

Note this might be related to #4499 both are failing gdalwarp. Though I don't have CUnit configured on Bessie yet.

They both have commonality of running Proj 6.1.0, however bessie is running GDAL 2.4.1 so may be more to do with proj than GDAL.

Disable raster failing tests

References #4379

I've disabled that test until the root cause is investigated.
