Hi Daniel,
does not start, as it goes back directly to the shell, or it seems 
stacked and typing "quit" it exits back to the shell ?

The first effect is caused by missing or mismatched DLL's.

The second I have seen on my W10 only if I run GDB from CMD and the 
Cygwin bin directory is not in the PATH
