Why does RegionCentroid crash on 2D-Polygons (WL V13.1)?

Werner Geiger

Use the following code which is copied from the reference documentation for RegionCentroid

reg = Polygon[{{0, 0}, {1, 0}, {1.5, 0.5}, {1, 1}, {0, 1}, {-0.5, 0.5}}];
RegionCentroid[reg]

This crashes with a Beep and an unitialized kernel and nothing else. No error message.

I have reported this issue to Wolfram support. They answered:

Werner

Thank you for reporting this. I am not sure what is happening on your machine as the code works as expected on my machine. It is possible you might have corrupt preferences that could lead to such behavior. Instructions for correcting that can be found here:

I have filed your report with our developers so they can investigate the issue.

Hi Werner,

Returns {0.5, 0.5} on "13.1.0 for Mac OS X ARM (64-bit) (June 16, 2022)". What platform are you on?

This happened with:

  • Windows 10 Pro (64-bit), 21H2, Build 19044.1949 - Wolfram|One 13.1.0
  • Intel(R) Core(TM) i7-3840QM CPU @ 2.80GHz 2.80 GHz
  • 16 GB RAM

I just tried it on:

  • Windows 11 Pro (64-bit), 21H2, Build 22000.918 - Wolfram|One 13.1.0
  • 11th Gen Intel(R) Core(TM) i7-11850H @ 2.50GHz 2.50 GHz
  • 64 GB RAM

There it works and returns {0.5,0.5}.

Strange! Why could such a simple calculation depend on the operating system or hardware?
