I only run one MINGW program on my computer and it is built at any epoch
under /d/bld/gdl/<name> and to run them I use
a bash shell. I set this shell up from a simple command prompt and use:
> target: c:\msys64\usr\bin\bash.exe -login -i
Start in: C:\msys64\usr\bin
This is in preference to running via the standard msys shell as the console
device acts properly for this setup.
Adding to the strange collection of symptoms, a recent build of the program
("GDL") now results in a successful
looking readout from "ldd" but hangs when I run the program:

So my initial conclusion is that the updated msys runtime seems to have
acquired some bugs.
