vtk_save() hangs on Windows with "AUX" filename

[juliohm]

Could you please confirm the following code hangs on Windows? It works just fine on Linux.

using GeoStatsImages
using WriteVTK

function writevtk(filename, grid)
    nx, ny, nz = size(grid)
    vtkfile = vtk_grid(filename, Float64[1:nx;], Float64[1:ny;], Float64[1:nz;], compress=false)
    vtk_point_data(vtkfile, grid, "facies")
    vtk_save(vtkfile)
end

function thickness(basin)
    AUX = repeat(sum(!isnan(basin),3), inner=[1,1,size(basin,3)])
    AUX = AUX / maximum(AUX)
    AUX[isnan(basin)] = NaN

    AUX
end

GRID = thickness(training_image("Flumy"))

writevtk("AUX", GRID)

The issue is the filename, whenever I set it to AUX, the code hangs on Windows.

@jipolanco can you reproduce the issue?

[jipolanco]

Sorry, I don't have windows, so I can't reproduce it.

• Is this with Julia 0.4?
• Does it hang after vtk_grid or after vtk_save?
• Could you test with other filenames: aux (lowercase), Aux, TEST?
• What is the output of UTF8String("AUX" * ".vtr")?

[juliohm]

I'll get back to you tomorrow when I have access to this Windows workstation again, I don't know why this particular name is causing the issue.

Answering all the questions:

• Yes, Julia 0.4.1
• It hangs somewhere in vtk_save
• It hangs with AUX and Aux, but doesn't hang with TEST
• The output is "AUX.vtr" as expected

Windows is weird!
