Can Guile be bootstrapped from source without psyntax-pp.scm?

Recently, I've read the chapter on Macros in Guile's manual. The manual
says that Guile's expander originated from that of Chez Scheme's and
that version was portable to other schemes as well. So I search the
Internet and find it[0]. The website states that the expander needs an
expanded version of itself for bootstrapping, i.e. needs
psyntax.pp for bootstrapping.

After playing for awhile, I realize the relationship of Guile's
psyntax.scm and psyntax-pp.scm is exactly analogus. One needs an
expanded version of psyntax.scm, i.e. psyntax-pp.scm for bootstrapping.

Does this mean Guile is not bootstrappable from source only? I've tried
to compile Guile 2.2.2 with psyntax-pp.scm removed and I get a
segfault[1]. It seems the interpreter relies on psyntax-pp.scm to
function properly. I don't know if I should bring this discussion to
guix-devel. Free to do so if you think it is on topic.
