Thanks for the report. That's a bug which was for some reason not caught by the CI. I guess it's a i686 only bug and IIRC that isn't tested right now.
I'll submit a fix later today or tomorrow.

I think this has been answered on the D newsgroup. -- Johannes |

It does. Now I have an issue with a language feature. With dmd v2.078.2 this
code compiles:
void function () [string] disp;
static this () {
enum typenames = ["float", "double", "real", "short", "int", "long"];
static foreach (s; typenames) {
pragma (msg, s);
disp[s] = mixin ("&mymain!" ~ s);
}
}
but gdc (GCC 4.9.4) complains:
dotbench.d:65:11: Fehler: basic type expected, not foreach
static foreach (s; typenames) {
^
dotbench.d:65:11: Fehler: no identifier for declarator _error_
static foreach (s; typenames) {
^

Maybe we'll get a static foreach backport soon (https://dlang.slack.com/ archives/C6LTP6MV1/p1519419332000480 ), otherwise static foreach will only start working once we switch GDC to the D frontend (https:// github.com/D-Programming-GDC/GDC/pull/550 ). -- Johannes |

I didn't come that far with the backport. Some bugs are very difficult to find (for me) and the D implementation uses some template features that aren't really translatable into pre-C++11 C++. So I'm not sure that I'll finish this. Especially I don't know if it is worth it. It depends how soon gdc will be merged with the upstream.
