crash on environment name beginning with non-ASCII char (64 bit)

crash on environment name beginning with non-ASCII char (64 bit)

[Thomas Wolff]

If an environment variable is set in the Windows environment that has a 
name beginning with a non-ASCII character (e.g. "äx", value "test"),
initialising the 64-bit cygwin dll fails:
*** fatal error - internal error reading the windows environment - too 
many environment variables?
No problem with the 32-bit dll. Also 64-bit works e.g. with a variable 
name of "aäx".

At first I assumed this was the ongoing ReadLine problem:

http://cygwin.com/ml/cygwin/2017-04/msg00176.html

in which case I would ask you to see if the problem persists with Dash, or if it
is exclusive to Bash. However I am not able to repro your issue. I tried it in
pristine Windows 7 virtual machine with:

- Cygwin desktop shortcut
- Cygwin.bat
- Directory\Background\shell reg key

However, even though I cannot repro this, it still seems like a ReadLine issue,
as it seems too similar to a similar problem I am having to be a coincidence:

Crap, I was confused by your wording. *I can* repro this if the variable *name*
begins with non-ASCII.

Sadly, this appears to affect Dash as well, so it goes all the way down to the
Cygwin DLL, as you said.
