Warning C4701: potentially uninitialized local variable 'Result' used

[Tw1ddle]

The following code:

glm/glm/detail/func_vector_relational.inl

Lines 8 to 18 in 0d973b4

	template<length_t L, typename T, qualifier Q>
	GLM_FUNC_QUALIFIER vec<L, bool, Q> lessThan(vec<L, T, Q> const& x, vec<L, T, Q> const& y)
	{
	assert(x.length() == y.length());
	vec<L, bool, Q> Result;
	for(length_t i = 0; i < x.length(); ++i)
	Result[i] = x[i] < y[i];
	return Result;
	}

Produces this warning with MSVC 2013 update 5:

include\glm\detail\func_vector_relational.inl(17): warning C4701: potentially uninitialized local variable 'Result' used

This isn't a bug because the Result vector is always populated in the loop, and there is already an assertion to check the lengths are equal to be sure. I guess it'd be wasteful to initialize the result vector at the beginning, but it would be nice to silence such warnings within glm.

Hi,
This issue should be fixed in master branch for GLM 0.9.9.1 release.
Thanks for reporting,
Christophe
