I'm not the author of this issue, but I can still replicate it. Same thing 72
bytes.

Compiling with both dmd and dub produces this leak and turning on -betterC
switch fixes issue.

Also, just a note, changing compiler to LDC makes it even worse (going to
report on their repo).

Since we now have proper valgrind support including a test in the test suite
(https://github.com/dlang/dmd/pull/15304), can you still reproduce this?
