Subject: Re: Problem using pthread and libc wrapper
Date: Thu, 21 Jan 2016 14:58:50 -0500	[thread overview]
Message-ID: <56A1387A.7090700__28119.9821424254$1453406447$gmane$org@efficios.com> (raw)

Hi Martin,

We have been able to reproduce the problem with yocto-fido with updated 
lttng 2.7.1 on a wanboard-quad(armv7rev10).

This is some weird behavior and so far we don't have a direct 
explanation. We have other arm boards with Ubuntu on it and we will 
check if we have any problems there to eliminate some hypothesis.
It's not only affecting the libc and pthread wrapped but also to the 
internal statedump provider etc.

We are working on it.

Thanks for reporting this and working with us on the issue.

Cheers
