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.
