Hi all guys,

I am experiencing error when testing 3.7.3. The error report is  
following:

The processor is Intel® Core™ i7-2640M CPU @ 2.80GHz. I use RHEL6.  
Has anybody experienced this prolem?

Hi Nemanja,

Any progress on this from your end? Sounds like no one else is having  
this  
issue, including me. Without being able to reproduce it, I’m not sure  
what  
else I can do.

Tom

Hi,

no, not any progress at all. I am still using good ol’ 3.6.5.1 🙂  
actually i don’t know what can be the problem and from where to start.  
I can provide all the info u need for solving the problem if that is  
important.  
And yes, I didn’t want to post again cause I thought nobody cares,so  
thank  
you.
