Magic infinite loop inside foreach

[MrSmith]

I have some function which does some matrix calculations and 
prints them. It is actually calculationg determinant of the 
matrix and i need to call those functions several times in the 
loop, until i get the final result. Here is the code.

void solveAndPrint(T : CoeffMatrix!(ElementType, ElementType), 
ElementType)(T _matrix)
{
	auto matrix = _matrix;
	TempMatrix!ElementType temp;

	foreach(_; 0..3) //3 is just for debug
	{
		writeln(matrix);
		temp = makeTemp(matrix);

		writeln(temp);
		matrix = solveTemp(temp);

		writeln("done1");
		stdout.flush();
	}
	writeln("done2");
	stdout.flush();
}

The problem is that after 'done1' is printed it is running 
infinitely consuming all the processor just like if has infinite 
loop inside. done2 is never printed.
