Erik Groeneveld updated PYLUCENE-58:
------------------------------------
Priority: Trivial (was: Critical)
> SEGV on import lucene
> ---------------------
>
> Key: PYLUCENE-58
> URL: https://issues.apache.org/jira/browse/PYLUCENE-58
> Project: PyLucene
> Issue Type: Bug
> Environment: Debian Buster, Python 3.7
> Reporter: Erik Groeneveld
> Priority: Trivial

> Hi Andy,
> Thanks again for your great work on PyLucene and JCC!
> Recently, after porting everything to python3, we get occasional SEGV's on
> shutdown. It happens very late, when the garbage collector starts cleaning up.
> Using python3-dbg exposed another problem however. With python3-dbg, "import
> lucene" already triggers SEGV. Here is the top of the backtrace:
>
