Red herring.

Issue 2787: Sanitize usage of -DDEBUG, -DNDEBUG and assert

The compiler option -DNDEBUG is no longer being used: -DNDEBUG disables
the assert function, and assert is essentially stating that the program
cannot useful continue if the assertion is not met.  -DNDEBUG is
basically an option for compiling an application to a limited amount of
ROM when aborting with a diagnostic is not preferable to crashing.

This is not the case for LilyPond.  So expensive debugging options now
are enabled with -DDEBUG instead.  There is a new configure option
--enable-checking defaulting to "off" for this now.

At the current point of time, setting --disable-optimising also has the
effect of enabling the checks: this will be retained until Patchy has
been adapted to using --enable-checking.

is 2.19.21 so if you actually want to find out what problem might be
there, you need to configure using --disable-optimising (for example)
for versions older than that.

Code below works fine when run under windows in lilypond 2.18.2
However when running in 2.19.83, or in 2.21.0 (version end November) an
