Re: seg fault w/ macro-module combination

Anything that segfaults with language input (and isn't a ccall) is automatically a bug. Please don't hesitate to file an issue at https://github.com/JuliaLang/julia/issues

I was hacking around trying to get a nice syntax to turn modules into self contained testblocks so I could do

@testblock testname begin

  @assert funtest(a) == 6
end

and it would automatically load up Base.* and my module file and provide stdout printing of test name etc.

I like the idea of modules being able to load up different environments.

Anyway I am getting seg faults with the code below.

tstfile.jl

macro testblock(name)

    quote

        module $name

        import Base.*

        a = 2

        end

    end

end

running

>julia tstfile.jl

results in:

Segmentation fault (core dumped)

And isn't an *incorrect* ccall. We've certainly had (rare) situations where correct ccalls caused segfaults. That's definitely a bug too.

I tried to reproduce this and haven't been able to. If this still
happens, file an issue with version and system details.
