The segfault was introduced in 3.0.0. 2.9.1 still works.

@jimmymasaru What exactly do you want to do here with -decid? The real problem here is that it's not possible to make a name-keyed font with this many glyphs so it never should have worked in the first place. It "worked" in older releases by making a bad file, but that was fixed in 3.0.0. If you want to manipulate a particular glyph or range of glyphs you can use the -g flag to get only those glyphs.
