I'm trying to understand this one: https://bugs.php.net/bug.php?id=75837
Is that related to the optimizations in 7.2 around unused local
variables? Can that somehow be triggered by the @ operator? It's such
a trivial reproduce case, it seems almost silly that this hasn't come
up during testing...

No $foo ?: 'default' , it's only equivalent to (isset($foo) && $foo) ?
$foo : 'default' if $foo exists.
Also PHP has added ?? as null-coalescing operator that works with
undefined variables/attributes/keys, my proposal is an improvement over
this one.
I don't want to endorse usage of undefin
This:
echo (isset($foo) && $foo) ? $foo : 'default';
Is equivalent to:
echo $foo ?: 'default';
Please don't endorse usage of undefined variables.

Related with Request #75833 https://bugs.php.net/bug.php?id=75833
From PHP 7 null-coalescing operator is a great option to avoid a
previous exists check with isset.
But I think that this comaparison can be improved adding a ternary
operator like ??: and check also empty values.
Example:

Hi PHP developers,
I am new and try to porting php v7.2.1 on IBM s390x, after building and
run unit test "make test", there are
some failed cases. Is there any way I can run a single case and get the
result?
Further how to debug a php unit case code?
