Hi,
My code runs fine on Win7 32bit and 64bit, Osx 64bit and Linux 32bit, but produces a seg fault on Linux 64. I'm using 2012 Composer XE.
Here is the back trace:
Program received signal SIGSEGV, Segmentation fault.
0x000000000081650b in dgeqp3_ ()
(gdb) bt
#0 0x000000000081650b in dgeqp3_ ()

#7 0x000000000048d401 in main (argc=3, argv=0x7fffffff9448) at FEBio.cpp:156
It's particulary curious since I'm using the same compiler on Linux 32 bit. Have you seen this error before?
Thanks,
Dave

Dave, We have not seen this issue before. Could you give the example? we will caheck it with the latest update of MKL 11.0.5? or you can evaluate it by himself.

Hi Gennady,
I realized that I was linking to the 10.2 version of the MKL. When I link to the MKL included with the 2012 Composer XE I get the following seg fault:
Program received signal SIGSEGV, Segmentation fault.
0x00000000011f724d in mkl_pds_lp64_blkldlslvs1_omp_pardiso ()
(gdb) bt
#0 0x00000000011f724d in mkl_pds_lp64_blkldlslvs1_omp_pardiso ()
#1 0x0000000000000000 in ?? ()
I've attached the code. Note that you will need to edit MKL_PATH and INTEL_INC in the Makefile.
Thanks for your help,
Dave

Good news. The MKL 11.0.5 version solved this problem.
Thanks,
