Subject [jira] [Commented] (LUCENE-3335) jrebug causes porter stemmer to sigsegv
Date Tue, 02 Aug 2011 11:11:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3335?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13076132#comment-13076132

Uwe Schindler commented on LUCENE-3335:
---------------------------------------

@Shay: Sorry I did not want to be too italian :-) I just wanted to ensure that such configurations,
leading to bugs in JVMs, would be reported to us. It would help us to also respond quicker
on such bug reports, like the one we already got 2 months ago (which nobody was able to reproduce,
as we did not know that the user used aggressive opts).
