Can you show how you declared these in D? It's important. I think what's
happening is that the nk_color_hex_rgb is incorrectly defined. I think
you should *always* get segfault, with or without any of those arrays.

I certainly can, but the problem is completely in C, I'm not having any
problems in D. In this case, I've simply copied the two functions to
test.c and inserted main(). Here are my implementations though:
nk_color nk_rgb_hex(string rgb)
{
if (rgb[0] == '#') rgb = rgb[1..$];
return nk_color(cast(nk_byte)nk_parse_hex(rgb[0 .. 2]),
cast(nk_byte)nk_parse_hex(rgb[2 .. 4]),
cast(nk_byte)nk_parse_hex(rgb[4 .. $]), 255);
}
private void nk_color_hex_impl(int n)(out char[] output, nk_color col)
{
output.reserve(n);
alias NK_TO_HEX = (i) => i <= 9 ? '0' + i : 'A' - 10 + i;
foreach(color; col.tupleof) {
output ~= to!char(NK_TO_HEX((color & 0xF0) >> 4));
output ~= to!char(NK_TO_HEX(color & 0x0F));
}
}
void nk_color_hex_rgba(out char[] output, nk_color col)
{
nk_color_hex_impl!8(output, col);
}
void nk_color_hex_rgb(out char[] output, nk_color col)
{
nk_color_hex_impl!6(output, col);
}
Not to happy with nk_color_hex_impl and family yet because I'm convinced
there is a better way but for now that's what I've got.
