Phillip Cloud commented on ARROW-1908:
--------------------------------------
In [~jorisvandenbossche]'s example the construction succeeds, but in the
following example the interpreter crashes:
{code}
In [1]: df = pd.DataFrame([(1, 'a'), (2, 'b')], columns=list('aa'))
In [2]: t = pa.Table.from_pandas(df)
{code}
> [Python] Construction of arrow table from pandas DataFrame allows duplicate
> column names
