Debug Random

[joaogoliveira1]

Hello,

So here is the issue: I am running a version of the following code:

function bogus(a)
    nsim = 1
    nsim2 = 2
    c = rand(nsim,nsim2) # breakpoint here
end

bogus(3)

At the definition of c, I put a breakpoint. I then run the debugger, and it stops a that point. I then run the line, and it issues the following error message:

ERROR: IOError: stat: unknown error (UNKNOWN) for file "D:\buildbot\worker\package_win64\build\usr\share\julia\stdlib\v1.4\Random\src\Random.jl"

The interesting thing is: when I run this code out of debugger mode, it runs fine. I'm running this code on Juno. This is my version:

Anybody come across this? Thanks

Side rand: The fact that isfile can throw is so so annoying.

We should probably fix the fact that isfile can throw. Is there an issue for that?
