Error on x86 machine

[KDr2]

I wrote a simple pkg, FlameSVG.jl, to generate SVG using flamegraph.pl, and added some test cases, incidentally found FlamsGraphs doesn't run on x86 machine, the error information is:

  MethodError: no method matching lineinfodict(::Array{UInt32,1})
  Closest candidates are:

Interestingly,

julia> data, lidict = Profile.retrieve();

julia> typeof(data) # on 32-bit systems
Array{UInt32,1}

julia> typeof(lidict)
Dict{UInt64,Array{Base.StackTraces.StackFrame,1}}

Given the portability of jlprof files, I think forcing conversion to UInt64 is safer than using UInt.

Although this may be an issue with Julia, sometimes the @profile freeze on 32-bit Windows (WOW64). However, I don't know how to reproduce the issue.:confused:
Moreover, there seems to be some problem with profiling on 32-bit systems other than Windows.

Edit:
The problem on Windows may be fixed by JuliaLang/julia#34454. (v1.0 has not been fixed yet.)
