And again test failures. This time, not with the new test, but as you
say, "Ah, tehe joy of fixing one problem only to uncover another." So
this time:
test/unittest/funcs/alloca/tst.alloca-funcs.d: FAIL: expected
results differ.
Diff against expected:
a/b
-8b11/b/b3a/b//baba
+18446671313727729520b11/b/b3a/b//baba
Here, "8" has become "18446671313727729520". So, need some .r change
(and some .r.p magic and possibly .d tweak).
test/unittest/funcs/alloca/tst.string-alloca.d: FAIL: expected
results differ.
Diff against expected:
-abc
+
Here, simply a bug?
