I wrote it 4 times:

- http://cygwin.com/ml/cygwin/2017-09/msg00289.html

Here though, let me write it 5 now:

   $ cat z.cpp
   #include <iostream>
   main() {
     std::cout << "cout test\n";
   }

   $ x86_64-w64-mingw32-g++ -static -o z z.cpp

   $ ./z
   Segmentation fault

> as in the past you blamed the compiler.

Yes, I discovered new information, so I modified the email subject to reflect
that. Would you rather me continue to blame the complier, or try to help
diagnose the problem?

See above - also notice carefully that example was included in my previous post
as well

No one but you has said that 2.28 has a problem. What Martchus actually said
was:

- 2.28   working
- 2.28.1 never tried
- 2.29   working

No

Hm. Last I checked I have already made at least 10 posts on this issue:

Maybe your sense of time is distorted.

Good for you, but I dont have to build anything to verify the issue - I narrowed
the problem to a single package, and tested with "Test" and "Current" versions.
"Current" works - "Test" fails.

So we could patch "Test", but since a newer version is already available (2.29),
the sane thing to do would be to just upload a newer test version and probably
bypass the problem altogether. If you want to waste your time making a build in
this case that is your business, but dont put that bad advice off on me when I
have already diagnosed the problem.
