 I posted this to the boost-user mailing list and it was recommended to
 file a ticket here.

 One must cast a variable as an unsigned int in the seed() function (even
 though the variable is declared as an unsigned int). Here's a minimal code
 segment that replicates the behavior:


 {{{
 boost::mt19937 rng;
 unsigned int rseed = static_cast<unsigned int>(std::time(0));
 rng.seed( rseed );  // This causes an error
 rng.seed( static_cast<unsigned int>(rseed) ); // This works
 }}}
