Dear Stehpen,

thanks for your fast answer. The different versions of libblas I tried with are:

for R2009a : 10.1.1
for R2011b : 10.3.2
for R2012a : 10.3.5

Intel(R) Math Kernel Library Version 10.1.1 Product Build 082212.12 for Intel(R) 64 architecture applications

Intel(R) Math Kernel Library Version 10.3.2 Product Build 20110112 for Intel(R) 64 architecture applications

Intel(R) Math Kernel Library Version 10.3.5 Product Build 20110720 for Intel(R) 64 architecture applications

Hi,

I'm using the wrapper in the laptop using ubuntu 32bit. I works perfectly.

However, as desktop machine I have a 64bit processor and both tests crash. I can compile successfully and the crashing point is arbitrary: sometimes at iteration 4, sometimes in the beginning, depending on the Matlab version.

I tried with R2009b, R2011b, R2012a and always crashes. I also tried with both 4.4 and 4.3 gfortran and gcc. What could be the problem?

I'm using:

Intel(R) Core(TM)2 Duo CPU E8500 @ 3.16GHz
Linux 2.6.32-41-generic #90-Ubuntu SMP Tue May 22 11:29:51 UTC 2012 x86_64 GNU/Linux
