I've reproduced this fail.
If I understand correctly, the cause is an issue of FreeType 2.6 and 2.6.1.
https://savannah.nongnu.org/bugs/?46130

FreeType 2.5.5 and earlier do not have this issue.
FreeType 2.6.2+ is fixed it.

Since I've changed from "error" to "warning" at Patch Set 2, LilyPond is no longer stop.
However, the warning messages like the following are shown if you use FreeType 2.6 or 2.6.1.

warning: cannot get font TeXGyreSchola-Regular CFF name

Moreover, for non-Japanese font in NotoSansCJK.ttc, PDF output is failed because LilyPond cannot get CFF name.
For other fonts, PDF output is no problem even if the warning messages are shown.

Again, FreeType 2.6.2+ is fixed this issue.
The warning messages are not shown.
Non-Japanese font in NotoSansCJK.ttc can be used for PDF output.

However, FreeType 2.6.1 seems to have been widely used in Ubuntu 16.04 LTS etc.

Would you think measures are required?

If I understand correctly, this caused by FreeType 2.5.5 or earlier.

For example, if you use a non-Japanese (e.g. Chinese or Korean) font in NotoSansCJK.ttc ver. 1.004, FreeType 2.5.5 gets a Japanese postscript name.

Therefore, LilyPond might embed the fonts with wrong postscript name if you use FreeType 2.5.5 or earlier.
Even if the name is wrong, the glyphs are correct.

FreeType 2.6+ is fixed it.

For LilyPond official site's binaries:
Current GUB uses FreeType 2.4.12.
So I'm making the GUB's patch which update FreeType.

For others:
Bump up required or recommended version of FreeType?
