Segfault in eval

[andreasnoack]

It might not be supported to macroexpand and evaling a macro call with @enter but it probably shouldn't cause a segfault either. On laster commit of this package I get

julia> using DistributedArrays

julia> using Gallium

julia> @enter eval(macroexpand(:(@DArray [1 for i = 1:3, j = 1:3])))

234   eval(m::Module, e::ANY) = ccall(:jl_toplevel_eval_in, Any, (Any, Any), m, e)

I also get a segfault with a breakpoint

Gallium.breakpoint(mapfoldl)
@DArray [1 for i = 1:3, j = 1:3]

...segfault...
