Hi,
As I wrote in the preceding post ...
Using Corinna's latest snapshot in a "Dos box" results in a
prompt from bash.
Once in bash, I can launch MinTTY ( 64-@@ /usr/bin/mintty )
Placing strace in front of this call, results in:

There's also another dll reported from winsxs rather than System32 in
your log. Maybe some files got corrupted on your system?
I can reproduce this but while it's clear *where* it happens, it's
unclear *when* and *why* it happens.
Unclear to me what exactly can be reproduced. With today's snapshot
cygwin1.dll, I can start mintty any way, also from Explorer, via
shortcut, or directly from cmd.exe (skipping cygwin shell).

It only occurs if mintty is the first process in a process tree. I.e.,
when starting mintty from a shell running in a DOS window, the problem
disappears.
Worse, the problem also disappears when running mintty under gdb.
