--------------------------------------------
Summary: [C++] JSON reader segfaults on newline
Key: ARROW-6762
URL: https://issues.apache.org/jira/browse/ARROW-6762
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Joris Van den Bossche
Using the {{SampleRecord.jl}} attachment from ARROW-6737, I notice that trying
to read this file on master results in a segfault:
{code}
In [1]: from pyarrow import json
...: import pyarrow.parquet as pq
...:
...: r = json.read_json('SampleRecord.jl')
WARNING: Logging before InitGoogleLogging() is written to STDERR

(string_view(*next_partial).find_first_not_of(" \t\n\r")) ==
(string_view::npos)
*** Check failure stack trace: ***
Aborted (core dumped)
{code}
while with 0.14.1 this works fine:
{code}
