[jira] [Updated] (ARROW-2082) SegFault in pyarrow.parquet.write_table with specific options

     [ https://issues.apache.org/jira/browse/ARROW-2082?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Clément Bouscasse updated ARROW-2082:
-------------------------------------
    Description: 
I originally filed an issue in the pandas project but we've tracked it down to arrow itself, when called via pandas in specific circumstances:

[https://github.com/pandas-dev/pandas/issues/19493]

basically using
{code:java}
 df.to_parquet('filename.parquet', flavor='spark'){code}
gives a seg fault if `df` contains a datetime column.

Under the covers,  pandas translates this to the following call:
{code:java}
pq.write_table(table, 'output.parquet', flavor='spark', compression='snappy', coerce_timestamps='ms')
{code}
which gives me an instant crash.

There is a repro on the github ticket.
