Ah, I got understanding. The reduced case in comment#3 has generated wrong code
with -inline, since the change by PR#4474:
https://github.com/D-Programming-Language/dmd/pull/4474

However, comment#3 and comment#4 are essentially same. The only one difference
is the parenthesis on stdout.lockingTextWriter(); in writeln template function.
So, this wrong-code issue in the comment#3 case was hidden by issue 14264, and
it's *fixed* by PR#4474. Therefore the two cases can hit this issue with
current master.
