evaluation mode is broken on julia v1.11

[bjarthur]

works fine in julia v1.10.9 with Debugger v0.7.10 (see below REPL transcript), but with julia v1.11.5 and Debugger v0.7.12 it hangs after x.

julia> f(x) = x+1
f (generic function with 1 method)

julia> using Debugger
Precompiling Debugger finished.
  5 dependencies successfully precompiled in 6 seconds. 1 already precompiled.

julia> @enter f(2)
In f(x) at REPL[2]:1
>1  f(x) = x+1

About to run: (+)(2, 1)
1|julia> x
2

What Debugger version?

[bjarthur]

the julia and debugger versions are in the original post. did you mean to ask about sth else?

[bjarthur]

hangs on julia v1.12-beta2 with Debugger v0.7.12 too.

Running into the same issue. Not sure if it's helpful, but this is the stacktrace when ctrl+cing the hang.

Could it be the same as JuliaDebug/Infiltrator.jl#139?

[serenity4]

I see that a similar fix was done in #367, though I'm wondering if we need something more than slapping a @spawn on it.
