Details about bugs fixed

Hello,

I would like to know details about bugs fixed.
More specifically, I would like to know more details about the following fixed at the TBB 3.0 update 3.

- Fixed a data race in task scheduler destruction that on rare occasion could result in memory corruption.

What should I do for getting to know details about it?

I appreciate your help.
Thanks.

Hello Daigoro,

you can run diff on sources for TBB 3.0 update 2 and TBB 3.0 update 3 to get more details.

I'm not sure what anyone remembers any details about the bug fixed 4 years ago.

I would advise to first check CHANGES, then do a web search, and only run diff if you like headaches. :-)

I thought the documents of bugs fixed exist in somewhere.

I encountered a problem using TBB 3.0 update 1.
Does Intel have support of problem analysis? 

Thanks.

I suggest trying TBB 4.2 update 5 from https://www.threadingbuildingblocks.org/. it should be fairly easy to upgrade TBB.

In case you still see this problem you can report it to this forum. If you have a commercial license you can submit an issue via Intel Premier Support site, in this case our support engineers will take at it.

If you want to check whether you have memory corruption either during the run or at the exit you can check it with Intel Inspector (https://software.intel.com/en-us/intel-inspector-xe)
