This program

void main()
{
    assert(0);
}

prints this on x86_64:

core.exception.AssertError w(3): Assertion failure
----------------
----------------

_All_ stack traces look like that on x86_64. For this one, if I were to compile
with -m32, I'd get this:

core.exception.AssertError w(3): Assertion failure
----------------
./w(onAssertError+0x2e) [0x806111e]
./w(_d_assertm+0x16) [0x805f096]
./w() [0x805ca76]
./w(_Dmain+0xd) [0x805ca61]
./w(_D2rt6dmain24mainUiPPaZi7runMainMFZv+0x1a) [0x805f53e]
./w(_D2rt6dmain24mainUiPPaZi7tryExecMFMDFZvZv+0x20) [0x805f1d8]
./w(_D2rt6dmain24mainUiPPaZi6runAllMFZv+0x32) [0x805f582]
./w(_D2rt6dmain24mainUiPPaZi7tryExecMFMDFZvZv+0x20) [0x805f1d8]
./w(main+0x94) [0x805f184]
/usr/lib32/libc.so.6(__libc_start_main+0xf3) [0xf75aa233]
----------------

So, this is purely a 64-bit issue. But the lack of stacktraces on x86_64 is a
definite impedement to debugging, and it really needs to get fixed.

Something that's never worked isn't a regression.  I agree it's a major feature
gap for x86-64 though.

I'm pretty darn sure that this was working before - hence why I changed it to
regression. I'd have to go try older versions of dmd to be 100% sure though.
But I have no problem with it being labeled critical instead of regression even
if it is a regression. It's making my life _much_ harder when it comes to
debugging.

This works now and has for a couple of releases, I believe.
