printf printing beyond bounds

[christarazi]

As I was playing around with Arbitrary Precision Arithmetic and tried to print sqrt(2), julia began to return strings way beyond its relevant scope.

Code:

with_bigfloat_precision(2048) do
    x = BigFloat(sqrt(2))
    @printf("%.1024f", x)
end

This would return:

Setting printf to print up to 10,000 will print a section of the documentation, really strange.

This seems like an obvious @JuliaBackports
