followup #360

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

looks like the dump is never written

[gillins]

So still doesn't give us the stack dump for SIGSEGV? Is this masked somehow?

[gillins]

Seems there is some crash handling here: https://github.com/qgis/QGIS/blob/1d63d5fce9ff1193df6a4c4690416471ed039008/src/app/main.cpp#L532 but maybe this isn't working like it should on OSX?

[m-kuhn]

To reproduce locally, will I need to build or can I install from some repo?

[gillins]

You should be able to just conda install qgis.

[gillins]

Or:

conda create -n testqgis qgis
conda activate testqgis

To be safe and create in a brand new env.

[gillins]

Although if you want a Debug build you'll need to do it yourself. See the build-locally.py script in this repo.

[m-kuhn]

Is there also an option to get a python debug build?

[gillins]

Seems support has been recently added for Debug Python builds here: conda-forge/python-feedstock#597 - I couldn't actually follow how to do this but maybe you have more patience.
Not sure if all extensions need to be rebuilt in debug mode also?

@m-kuhn can we close this one or you plan to keep working on it?
