This release
https://bitbucket.org/goshawk/gdc/downloads/gcc-4.6.1-tdm64-1-gdc-7e22befef29c-20111218.7z

All MinGW GDC downloads.
https://bitbucket.org/goshawk/gdc/downloads

All patches, source files and build scripts can be found at https://bitbucket.org/venix1/mingw-gdc/

I will be updating to tip and making -v2 default for the next release.

It compiles all of my dwinsamples (although I have to verify if I've introduced any 32/64 bugs), great work on the release!

Nice work.  One question, though:  Why are you using an ancient revision of GDC?  I'll try your build out, but I'm not sure most of my code still compiles on 2.055.  That's **two** releases behind now, and two very significant releases.

GDC support for 2.056 and 2.057 is less than 2 weeks old.  I didn't see it beneficial to update while testing a new feature.  Now that the support is there, I will be updating to tip.

Seems to work in 32-bit mode, but crashes in 64-bit mode.

hello.d:

import std.stdio;

void main() {
   writeln("Hello, world.");
}

>gdc -o hello.exe hello.d -m64 -v2

>hello.exe

(crash)

Running Windows 7, TDM-GCC 64 installed with the bundle installer.

I think it compiles in 64bit mode by default. This assert passes without -m64: static assert(size_t.sizeof == 8);

The crash seems related to stdio. It doesn't happen with -m32.

Woops, sorry I assumed you meant it doesn't, but you didn't say that. My bad. :)

...And with D1, everything works again in 32-bit mode but in 64-bit mode:

Yeah, I just added the -m64 to the command line for explicitness.
 I figured out that 64 is the default.

That's an oversight on my part.  binutils linker scripts don't follow the Win64 ABI.  The variables are still being defined as __data_start__ and __bss_end__ by the linker scripts.  I forgot to change the symbols for D1.

Regarding this and your previous issue, I just updated to tip.  So it may be a few days before I can upload new/fixed binaries.
