About G'MIC and system32\cmd.exe

When I tried the filter on the G'MIC, the command prompt started for a moment (I feel like I wrote system32\cmd.exe) and disappeared immediately. Is this normal operation?

Question
Q1. Is cmd.exe starting (sometimes) normal behavior when I run a filter on the G'MIC?

 The G'MIC defines a lightweight but powerful scripting language (G'MIC language) dedicated to designing image processing operators and pipelines.

Q2. About Filter Maintenance
There are more than 500 available filters, do you think this filter is maintained?
I'd like to know if it's just a filter that's been added before (due to interversion differences), or if I should be careful because it's a flow that makes it easy for anyone to stock up on scripts...
