Can you share a test case to investigate this?
As in the ThreadedFunctionsList.txt, ippmQRDecomp and ippmQRBackSubst are thereded. So I like to know how you are threading and what will be Environment variable value(OMP_NUM_THREADS)?
Did you verified any threading issues like deadlock or Concurrency using Intel Parallel Studio XE 2011?
Thanks for info..
I am not aware of any issues related to these two function- ippmQRDecomp and ippmQRBackSubst.
Test case would be better to verify it.
