Hello,
I have a weird problem in the code attached. When OMP_NUM_THREADS=1, I don't have any segmentation fault. When OMP_NUM_THREADS>1, it segfaults, unless I uncomment the lines 56 to 60 (i.e. if I first compute Ax, then A^T x'). Do you see where might be the problem ? I'm using icpc version 13.0.0 (gcc version 4.7.0 compatibility) on a Debian comp. Could this be linked to my (currently unresolved) other problem http://software.intel.com/en-us/forums/topic/336409 ?
Thanks in advance for your help.
Compiler is called as follows: icpc dcsrmv_segfault.cpp -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5
LDD returns:
