SEGFAULT in mkl_dcoomv() on Xeon Phi

$

I keep getting segmentation faults within mkl_dcoomv() function from MKL invoked in a native mode program on Xeon Phi (KNC). The code works well on the host (Haswell) as well as with the CSR strorage format (mkl_dcsrmv()) instead of COO. So, the problem happens only with the combination of COO an MIC.

In a debugger, I got the following error message:

Catchpoint -1 (signal SIGSEGV), 0x00007ffff514cc8a in mkl_spblas_lp64_dcoo0ng__c__mvout_mic () from /apps/all/imkl/2017.0.098-iimpi-2017.00-GCC-5.4.0-2.26/mkl/lib/mic/libmkl_intel_thread.so

The MKL and compiler versions are both 2017.

The code can be found here.

Any hints?
