[julia-users] type mismatch weirdness

[J Luis]

Hi, this is a continuation of what I by mistake posted in devs-list

https://groups.google.com/forum/?fromgroups=#!topic/julia-dev/GojOx4nI-xo

that now stroke me again (in another place)

function imcdCanvasPutImage(_canvas, _image, _x, _y, _w, _h, _xmin, _xmax, 
_ymin, _ymax)
    println("typeof(_image): ", _image)
    println("isa(_image, Ptr{imImage}): ", isa(_image, Ptr{imImage}))

which when execute prints this astonishing conclusion

C:\programs\Gits\IUP.jl\src>c:\programs\julia64\julia execa.jl
typeof(_image): Ptr{imImage} @0x0000000000180c30
isa(_image, Ptr{imImage}): false

However, when I try to reproduce this on the REPL, than it works
