I'm not sure but it looks to me as though the random lib has a few problems, 
I've run the tests on Linux/Itanium and Linux/Xeon using the HP testdrive 
machines, and there are (different) failures on both.  The logfiles are 
attached, but the segfault has the following backtrace:

(gdb) run

I can reproduce this with just

#include <cmath>

int main()
{
   long double d = std::tan(-0.53682426991417537756471137222469281L);
   return d;
}

So I'll file a bug report with Intel.

HTH,

John.
