Base.compilecache_path is misbehaving

[vtjnash]

As a pure function of the inputs, I'm not sure why this is no longer giving the same answers:

julia> Base.compilecache_path(Base.identify_package("Pkg"))
"/home/vtjnash/.julia/compiled/v1.6/Pkg/tUTdb_75wtU.ji"

julia> Base.compilecache_path(Base.identify_package("Pkg"))
"/home/vtjnash/.julia/compiled/v1.6/Pkg/tUTdb_Y4Mh0.ji"

Could you put some @show around

julia/base/loading.jl

Lines 1286 to 1291 in b08ad36

	crc = _crc32c(something(Base.active_project(), ""))
	crc = _crc32c(unsafe_string(JLOptions().image_file), crc)
	crc = _crc32c(unsafe_string(JLOptions().julia_bin), crc)
	crc = _crc32c(get_preferences_hash(pkg.uuid), crc)
	project_precompile_slug = slug(crc, 5)
	abspath(cachepath, string(entryfile, "_", project_precompile_slug, ".ji"))

to see what is different between the invocations?
