As per IEEE Std 1003.1-2017, Section 8.3, TERM and SHELL vars says we are running GIMP on POSIX shell. They are not set by either the deprecated Windows CMD nor by Windows PowerShell since they are not POSIX. POSIX shells are supported by us on Linux and macOS but actually not on Windows, since they are non-native: they rely on forking to Cygwin which have terrible performance (##11385) and do other tricks to make deps believe they are on Unix which breaks e.g. GObject Introspection (#11424). Anyway, it is Unix emulation at its prime, tricky by nature. Even so, does not hurt allow the output on these unsupported shells on Windows so not disrupt workflows of adventurous developers but they will be warned that problems (like the ones above) can and indeed appear.

|
|
* is a separate executable is simply that when the program crashed,
|
|

|
|
* errors and signals, it may not be possible to allocate memory
|
|
* anymore. Therefore creating a new dialog is an impossible action.
