Hey all, Is there anyone else that has a proc with HLE and is having issues with glibc? The newer Haswells have this and for a while now teamviewer has been refusing to launch on my system. Then more recently I installed pgAdmin3 and while it actually ran, there were actions that would set it off too. Turns out it was general protection fault, and a core dump seemed to show elision as the culprit. I've since rebuilt glibc x86_64 and the 32 bit libs without the enable-lock-elision flag which "fixes" the issue, but I'd like to know if anyone else has experienced this. -- Paul
TIL about Lock elision. Thanks Paul! http://lwn.net/Articles/534758/ On Tue, Mar 18, 2014 at 10:39 AM, Paul Sierks <psierks@sierkstech.net>wrote:

I don't have anything yet with HLE (interesting idea!), but it definitely sounds like it's bug submission time. If you can readily reproduce on 2 diff userspace apps, and make the bug go away with a make flag, then the bug should be handled quickly by upstream. Hopefully.
