I think I've seen this in CI before; never tracked it down though.

Thank you for filing this issue.

Yeah, it's only happening on 1.8, right? I think we should report this on the julia repository. it's a regression (or at least a change) in the Profile package that's causing this failure in a very simple test:

PProf.jl/test/PProf.jl

Lines 29 to 39 in 34c8724

	@profile for i in 1:10000
	# Profile compilation
	@eval foo(x,y) = x * y + x / y
	@eval foo($i,3)
	end
	# Cache profile output to test that it isn't changed
	_prior_profile_output = Profile.retrieve()
	# Write the profile
	outf = pprof(out=out, web=false)

I actually don't know if this means PProf CPU profiles are entirely broken on julia master? or if this test is somehow hitting some weird corner case?

But we should definitely file this as a regression on the julia repo 👍 👍

I am also experiencing this issue on a recent master build of Julia.

I've finally filed JuliaLang/julia#44818 about it. Sorry, should've done this weeks ago.
