And still that implied rigor that is inherently built into the official
building process did NOTHING to prevent it from delivering a product
that is 100% broken on macOS. Prey tell, how many tests in said suite
did it pass?
But maybe I am misunderstanding you. Is something like this (see
attached log) what you are referring to or is there some other specific
testsuite that it must pass to be considered a successful build?
Look, all I'm saying is that if I can build the compiler and use it to
compile itself on macOS, then there is something wrong with the way it
is being built in the release process. I am not in any way suggesting
that v2.112.0 does not introduce regressions or other bugs.

The build requires using ldmd2 (as a wrapper for ldc2) and gmake (GNU Make
4.x, as the system make is too old). Two issues were identified during
testing:
1. Critical: A bug in phobos/std/path.d causes a crash (Out of Memory) on
macOS. A patch is required for tests to pass.
2. Non-Critical: A test in phobos/std/socket.d fails due to missing IPv6
reverse DNS records on the network, but this is a "soft" failure that is
ignored by the test runner by default.
Issue Details
1. Crash in std.path (Fixed by Patch)
* File: phobos/std/path.d (around line 4120)
* Cause: The function expandFromDatabase calls getpwnam_r. On macOS, when the
buffer is too small, it returns ERANGE (34) but sets errno to EINVAL (22).
The existing code switches on errno, hits the default case, and throws
onOutOfMemoryError.
* Fix: The code should switch on the return value (passResult) which
correctly contains ERANGE, allowing the loop to resize the buffer and
retry.
2. Flaky Test in std.socket (Ignored)
* File: phobos/std/socket.d (Line 1006)
* Message: Ignoring std.socket(1006) test failure...
* Cause: The test resolves www.digitalmars.com and expects the reverse DNS
lookup of the resulting IP to match the hostname. On your network, it
resolves to an IPv6 address (2607:fc50:...) which lacks a PTR (reverse DNS)
record, causing the assertion to fail.
* Impact: This is a "soft" failure handled by softUnittest in the test suite,
so it does not fail the build unless -debug=std_socket is passed. No action
is needed.
