I need an old version of Intel TBB... where can I get it?

Hi,

I need to compile a program, which apparently needs Intel TBB version 3.x in order to run properly

I tried, of course, linking Intel TBB 4.2 and compiling it with appropriate flags and include directories, without any success...

Is there somewhere I can get such an old version of TBB?

multifun_node try_put() several messages to one successor crashes

Hi,
I'm connecting a multifun_node to a limiter_node, with the intention to send 0,1, or >1 messages to keep the flow well saturated. It works well with the concurrency threshold, nparqueue = 1, but throws an exception when nparqueue = 2. Please help!
