can't use ipy -X:Frames -c “import scipy” for IronPython

Question

i'm trying to use Scipy in my IronPython project, It's said that SciPy packages make use of Cpython's stack frame inspection capabilities and by default these are not enabled in IronPython, so we have to use

ipy -X:Frames -c "import scipy"

in command prompt, or in the Visual Studio we have to go to

tools/options/python tools/interactive windows/

and in the interpreter options type "-X:Frames "

but in the Visual Studio i always get the error "assertion failed" (i put the link of the images in below), which forces VS to be closed

Any suggestion? thanks in advance
