Glyphs crashes when custom parameters are "disable subroutines" and "rename glyphs"

When the custom parameter of an Export instance is “Disable Subroutines: true” and “Rename glyphs: one.alternate=one” the app Glyphs 3 crashes.
The crash occurs on export.

Probably important in this context is that one.alternate is a complex glyph with many nodes; hence the Disable Subroutines–it does not seem to allow me to export without it.

Can you send me that file?
