Antoine Pitrou commented on ARROW-5565:
---------------------------------------
I don't think you need "env" in that command? However you need the actual
executable to appear as first argument, e.g.:
{code}
gdb --args python -m pytest pyarrow/tests/test_array.py
{code}

> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Wes McKinney
> Priority: Major

>
> It may not be obvious to new developers how to set breakpoints in the C++
> libraries when driven from Python. The incantation is slightly abstruse, for
> example
> {code}
> $ gdb --args env py.test pyarrow/tests/test_array.py -k scalars_mixed_type
> {code}
