On commit [`526b83e3f1`](https://github.com/JuliaLang/julia/commit/526b83e3f168ef74515d73918135936565f80078) I’m seeing this strange message:

```julia
julia> using SpecialFunctions

julia> erfcinv(0.5)
in erfcinv at /home/mose/.julia/v0.7/SpecialFunctions/src/erf.jl
0.4769362762044699

julia> erfcinv(0.5)
0.4769362762044699

```

The message “`in erfcinv at /home/mose/.julia/v0.7/SpecialFunctions/src/erf.jl`” is shown only on the first call to the function. Does someone have a clue about where this message comes from?

Note that the message is printed also without loading `SpecialFunctions`, so it has nothing to do with the package, the only difference is that an error is printed in this case because the function was moved to an external package.

Culprit found after bisection: [PR#22763](https://github.com/JuliaLang/julia/pull/22763). The message is mentioned there.

Fixed in [https://github.com/JuliaMath/SpecialFunctions.jl/pull/36](https://github.com/JuliaMath/SpecialFunctions.jl/pull/36), though Julia should also be updated to give a better error message (the problem was SpecialFunctions importing a deprecated binding).
