FWIW, I recently tried the same procedure in a macOS 12.1 VM
(x86_64-apple-darwin21.2.0). This time, the build succeeded and test
results are reasonable
=== gdc Summary ===
# of expected passes 11587
# of unsupported tests 2
=== libphobos Summary ===
# of expected passes 556
# of unexpected failures 7
# of unsupported tests 1
although I had to rerun the libphobos tests sequentially since several
would time out otherwise.
There's one caveat, though, that applies equally to Mac OS X 10.7 and
macOS 12.1: at least some of the stage1 dependency lists in gcc/d/.deps
are corrupt in that they contain D source code after the dependencies
proper, e.g. gcc/d/.deps/hash.Po:
d/root-hash.o: /vol/gcc/src/hg/master/darwin/gcc/d/dmd/root/hash.d
is.value == c.value;
}
override size_t getHash(scope const void* p) @trusted const
{
return getArrayHash(value, p, len);
}
[...]
I cannot yet tell if this is just an issue with GCC 11.1.0 gdc or
libphobos that's fixed in 11.2.0 or gcc-11 branch.

It could be this patch fixes that.

It was requested to be backported back in November.

FYI, with darwin, I've only been using the most recent commit in
releases/gcc-11 for testing as there have been a number of issues exposed from
that port.
I have VMs set-up running 10.4 (PPC), 10.6 (x86_64), 10.13, 10.14, 10.15, 11,
and 12. Not yet gotten round to building a bootstrap compiler from gcc-11 just
yet though for testing build of master.

Seems quite plausible indeed. I'll give the top of the gcc-11 branch a
whirl on both 10.7 and 12. Maybe that's all it takes to get working
bootstrap compilers.
I previously took gcc 11.1.0 simply because I had the tree still around.

Good to know. Once the gcc-11 builds are done, I'll retry bootstrapping
master on 10.7 and 12. Maybe the SEGVs on 10.7 stage1 will be gone that
way...

I've now done just that:
* build top of gcc-11 with --enable-languages=d --enable-libphobos
* use that as bootstrap gdc for master
Results are pretty good:
* The corrupted *.Po files in stage1 are gone.
* On 10.7, the d21 SEGV is gone
* gdc and libphobos testsuite results on both 10.7 and 12 are
reasonable.
There's one caveat, though:
On 10.7 (so far), a couple of files don't compile building stage2 libphobos:
dyld: Symbol not found: __D6object10_xopEqualsFxPvxQdZb
Referect10_xopEqualsFxPvxQdZb
Referenced from: /var/gcc/regression/mnced from:
/var/gcc/regression/master/10.7-gcc/build/./gcc/d21
Expected in:
/var/gcc/regression/master/10.7-gcc/build/x86_64-apple-darwin11.4.2/libphobos/src/.libs/libgphobos.2.dylib
in
/var/gcc/regression/master/10.7-gcc/gcc/regression/master/10.7-gcc/build/./gcc/d21
and indeed that symbol (object._xopEquals(const(void*), const(void*)))
is missing from the freshly built libgphobos, while it is present in the
gcc-11 one.
I suspect this happens because the toplevel Makefile sets
DYLD_LIBRARY_PATH, since when I just run make in
x86_64-apple-darwin11.4.2/libphobos, the build succeeds without further
problems.
There are two issues here, I believe:
* The one line patch to gcc/config/darwin.h to support -static-libphobos
should be backported to the gcc-11 branch to avoid this in the first
place.
* Besides, making incompatible changes to libgphobos (like removing an
exported interface) shouldn't be done without increasing the library
version number.
