Blueprint plugin cannot read output from XRayImage Query on Windows

[biagas]

Describe the bug

I was running the regression suite on Windows , noticed crashes with xrayimage query.
I extracted enough code from the test file to run just one of the tests failing.

The issue comes up when a full-path is specified for the XRayImage query's output.

Here's the script: (TestingStuff.py contains methods to handle test-specific methods like Test and silo_data_path)

Source("TestingStuff.py")

def calc_midpoints(arr):
    midpts = []
    for i in range(0, len(arr) - 1):
        midpts.append((arr[i] + arr[i + 1]) / 2)
    return midpts

OpenDatabase(silo_data_path("curv3d.silo"))
DefineScalarExpression("d1", 'd')
DefineScalarExpression("p1", 'p')
DefineScalarExpression("d2", 'd * 6')
DefineScalarExpression("p2", 'p * 6')
DefineScalarExpression("d3", 'd * 3')
DefineScalarExpression("p3", 'p * 3')
DefineArrayExpression("darr", "array_compose(d1,d2,d3)")
DefineArrayExpression("parr", "array_compose(p1,p2,d3)")
AddPlot("Pseudocolor", "d")
DrawPlots()

# common place for args
divide_emis_by_absorb = 1
origin = (0.0, 2.5, 10.0)
theta = 0
phi = 0
width = 15
height = 10
image_size = (300, 200)

energy_group_bounds      = [0, 2, 6, 8]
fake_energy_group_bounds = [0, 1, 2, 3]

energy_group_midpts      = calc_midpoints(energy_group_bounds)
fake_energy_group_midpts = calc_midpoints(fake_energy_group_bounds)

calltype = "legacy"
output_type="hdf5"

# This outdir works
#outdir="."

# This outdir does not work
outdir="C:\\A_VisIt\\Run"

Query("XRay Image",
    output_type,
    outdir,
    divide_emis_by_absorb,
    origin[0],
    origin[1],
    origin[2],
    theta,
    phi,
    width,
    height,
    image_size[0],
    image_size[1],
    ("darr", "parr"),
    energy_group_bounds)

DeleteAllPlots()
DeleteExpression("d1")
DeleteExpression("p1")
DeleteExpression("d2")
DeleteExpression("p2")
DeleteExpression("d3")
DeleteExpression("p3")
DeleteExpression("darr")
DeleteExpression("parr")

CloseDatabase(silo_data_path("curv3d.silo"))

conduit_db = pjoin(outdir, "output.root")
OpenDatabase(conduit_db)
AddPlot("Pseudocolor", "mesh_image_topo/intensities")
DrawPlots()
Test("_image_topo_intensities_" + calltype)

Here is the relevant output from engine log when the query's output dir is: "C:\A_VisIt\Run"
Notice there is an extra Run in the path.

Here's the generated output.root in case it is helpful.
