... euh, I do not believe so (in my case) ... I installed v211 using setup,
which as
you know, does a full "rebase" ...
Also using 'setsid mintty' (in case of v113, v203) does not fail ...
> How much free memory do you have?
- my computer has lots of free memory (using less than 2 Gb of 8 Gb)
- my environment: using Cygwin (only the traditional tools)
- plus: Explorer (and most of the time: Process Explorer from SysInternals)
I am really surprised, that you (and others?) do not experience crashes (v211,
v212
if -D is specfied). Failure occurs consistent on my side.

... I expect ttyname() to return NULL, as mintty is a GUI application ... (and
it did, using
a "small GUI test program"; however it returned /dev/pty0 when executing it
from a dos console
in which mintty had been started). Yes, I am confused).
As I wrote 'and I asked myself', I was wondering about something like:
'getpid() != 1'
