[Qgis-developer] Issues with a Python test for Processing

[Germán Carrillo]

Hi All,


I'm having troubles trying to run a custom test [1] for my PR [2].


I'm able to run it against my local build in this way:

  $ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/apps/lib/
  $ QGIS_PREFIX_PATH=/apps
PYTHONPATH=/apps/share/qgis/python:/apps/share/qgis/python/plugins:$PYTHONPATH
python ../python/plugins/processing/tests/GdalAlgorithmsMemoryTest.py

It passes (prints OK) but I get a segmentation fault:

  ERROR 10: Pointer 'hDriver' is NULL in 'OGR_Dr_GetName'.
  *** Error in `python': double free or corruption (!prev):
0x0000000003a116b0 ***

When I push a commit to my PR, Travis says there are errors [3] with my
test, I guess related to file path configurations. Travis also gets the
segmentation fault.

Could someone please give me a clue on how to solve this issues?
Why tests pass against a local build but fail with Travis?


Regards,

Germán
