pgl.TriangleSet([],[]) causes conda terminated with exit code -1073741819 (0xC0000005).

Hi all,

I have just updated and specified the question:
This error can be reproduce on windows 10 with the following two lines.

import openalea.plantgl.all as pgl
pgl.TriangleSet([],[])

Which version of pgl are you using?
With conda list, I found that I have even two plantgl!

    openalea-plantgl         3.9.3           pypi_0                 pypi
    openalea.plantgl         3.9.3           py38h2272212_1         fredboudon

It seems that I am using openalea.plantgl, should** I switch to openalea-plantgl instead ?

Here you will find the current conda list result:
condalist_10_04_2022.txt
@pradal Could you please help me to find out where the problem is?

Many thanks,
Tien-Cheng.

Here is the background:
When I want to display the result of CaribuScene.run, the call of CaribuScene.plot() terminate the conda session without error messages

im3d = cache.load_image3d(snapshot, cache_client=cache_client)
# print("Reduction="+str(red))
vertices, faces = im3d.mesh(reduction=density)
triangles = {0: [[tuple(vertices[i]) for i in f] for f in faces]}
light = diffuse_source('16')  # authorized values : '1', '16', '46'
inter_plant = 1 / inter_row / density * 1e6  # in mm
pattern = (-inter_plant / 2, -inter_row / 2, inter_plant / 2, inter_row / 2)
cs = CaribuScene(triangles, light=light, pattern=pattern)
sr = cs.auto_screen(1)  # arg is in mm/pixel
raw, agg = cs.run(direct=True, simplify=True, infinite=True, screen_size=sr)
cs.plot(raw['Ei'])
