StackOverflowError when combining csv, hybridarrays and symbolics in 1.7

[judober]

When using CSV, HybridArrays and Symbolics in combination with 1.7.0, I get an StackOverflowError().
MWE (thanks @lawless-m):

using CSV, Symbolics, HybridArrays

function test1()
    CSV.File(""; delim = "; ", types = Float64)
end

test1()

The code works in 1.6.4.

Hmmm....I'm not sure what you're expecting CSV.File(""; ...) to do? it's not a file or valid csv data?

Are you expecting 1000s of lines of error messages and a crash ? Which doesn't happen without the presence of using HybridArrays, Symbolics

It is the same if it has a file, so taking the file out makes the MWE even more M than needing the file
