Thanks for finding the bug, and confirming that it is a bug and not just
a misunderstanding, and narrowing down the cause, and posting to bug-lilypond.

The relevant code did not change, but the version of GCC used as a cross-
operating-system compiler did change.  Some very useful programming
languages, including C,have details where behavior is allowed to vary
between systems, and here it seems LilyPond inadvertently depended on one
of those details.

There will probably be a couple more of these strange bugs in 2.19.16
