10924,conversion of float/double to cpp_dec_float_100 causes hang before main() on cygwin,anonymous,John Maddock,"It looks like g++ generates bad code for:

{{{
cpp_dec_float_100 x = 1.0;
}}}

A program with this line hangs with full cpu usage, never entering main(). If 1.0 is replaced with an integer the problem disappears. 

I'm using x86_64-pc-cygwin-g++ version 4.8.3, compiling with:
{{{
g++ -g -o gcc_bug_test1 gcc_bug_test1.cpp -I ""$BOOST_PATH""
}}}
on a fresh install using setup-x86_64.exe with mirror cs.vt.edu.

gcc_bug_test1.cpp : 
{{{
#include <iostream>
#include <boost/multiprecision/cpp_dec_float.hpp>

using namespace std;
namespace mp = boost::multiprecision;

int main(int argc, char *argv[])
{
	mp::cpp_dec_float_100 x = 1.0; // -3;
	return 0;
}
