Here's another update.

http://home.earthlink.net/~dvdfrdmn/d/d-for-gcc-r1d.tgz

* ICE when a struct was used before its definition

* Segfault on empty scope statements

* ICE for associative array properties
* Segfault on typedef'd floating point constants
* Handle calls to super

* Fix assignment ops on bit arrays
* Fix layout of struct stat for darwin

Thank you for fixing the bugs! It really helps me. I can already build
some D applications. gdc is great.

But I found more bugs.

bug_foreach.d:

int main() {
    /* it's safe
    int[] os;
    os.length = 2;
    */
    int[2] os;
    foreach (inout int o; os) {
        o = 0;   // segmentation fault.
    }
    return 0;
}

bug_not.d:

void safe() {
    bit b = !1;
}
bit bug() {
    return !1;   // cannot compile
}

bug_for.d:

void bug() {
    for (int i=3; --i; ) {}   // cannot compile
}

And, I cannot compile phobos's gcc/config.d on MacOSX.

$ make
gdc -o gcc/config.o -g -O2 -I ../../gcc/d/phobos -I
../../gcc/d/phobos/internal/gc -c gcc/config.d
gcc/config.d:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make: *** [gcc/config.o] Error 1

I think gdc-1d may not work on MacOSX.

The other bugs have been fixed in version 1e.  Please let me know if the
problems persist.

Hmm... I cannot reproduce the crash too on MacOSX. It may be only
linux's problem. I try to report a gdb trace. The crash happens with
linux-2.4.22 (Fedora Core1) and gcc-3.3.2 and gdc-r1e.

 As for config.d, I
 once accidently did a partial rebuild with the new gcc in the path and
 ended up with a gdc that did not work.  That's my best guess.


I'm sorry. It's my mistake. I built gdc with the gcc installed with
earlier gdc. It seems I should build it with MacOSX's gcc.
