crash with c++ compiler 15

When compiling the attached program with 

icc  -O3 -fp-model fast=2 -xCORE-AVX2 -fma -c -S mandel_cilk.cpp

 

I get ": internal error: 20000_3650". From https://software.intel.com/en-us/forums/topic/505663?language=it, it looks like this means there was a crash with the compiler.

Hi,

This issue can be worked around by removing the temporary array "test", which may also speed up the code:

  for(int k=0; k<max_count; ++k) {
     int rez = __sec_reduce_add(abs(z[:]) < 2.0f);
     if (!rez)

Thanks,

Reddy
