I'd say this is somehow related to 64-bit Cygwin programs being run by
32-bit native Windows programs.  The version which works for you is a
64-bit executable, those that don't are 32-bit.


Just to follow up on this for the sake of the archives, Eli is correct 
(no surprise).  The problem seems to be a result of recent changes to 
Windows 10, and Corinna is working on a fix.  See

Re: [h-e-w] cygwin-64 2.3.1. bash fails when running under FSF emacs 24.5

[Dominique de Waleffe]

Thanks, I'll look in that direction...

Next question is where can I find an official Emacs 64-bit build?

Went to the FAQ, read it at
(https://www.gnu.org/software/emacs/manual/html_node/efaq-w32/Downloading.html)
it says it should be on the ftp site  and there would be both a 32 and
64 bit versions but apparently there is only one of them, the 32
bit which I mistakenly took for the 64 bit. This probably
explains

Google a bit further, and it appears that some guy/team publishes a 64
bit build on sourceforge.
http://sourceforge.net/projects/emacsbinw64/ but it has nothing
official and it evolves along with the most recent sources apparently.

Just  now found
https://lists.gnu.org/archive/html/bug-gnu-emacs/2015-06/msg00729.html
discussing this issue :-)

BTW, I'll also give a try at the cygwin emacs build.

I'll also look at building Emacs from source for x64

Conclusion:
- I now have a version (25.xx) that works with cygwin64 bash
- FAQ still a somewhat misleading
- I'll have a look at building  Emacs from source and see how to
share the results.

Thanks anyway to all.

Re: [h-e-w] cygwin-64 2.3.1. bash fails when running under FSF emacs 24.5

[Dominique de Waleffe]

Before upgrading another machine (still on win7/64), I updated
cygwin64 on it and pulled fsfemacs 24.5 (the existing binary on gnu's
site) on it...

Did the same test there and on win7 it works. Could this be a Windows
10 related issue?

D.
PS: I'll stop cc'ing the emacs list after this message as I also think
it is more likely a cygwin issue.

So it looks like this is either a BLODA(*) problem, or rebasing the
entire distro is necessary(**).

[Dominique de Waleffe]

Corinna,
Thanks for the pointer.

I have checked the BLODA list. The only thing I have is windows
defender (part of the os:-(
It can be disabled via  group policy. (but I am not tempted to do that
for long term)
I did that but same issue...

I have rebased the whole cygwin as suggested also.
That did not fix the problem either.

I attached the bash stack trace in case it may help.

If you have any idea as to what I could do to help debug this... I'll
be happy to help.

Meanwhile, I'll make a VM with a fresh install of Win10 (v1511 x64)
and just Emacs + cygwin and see whether there is something fishy about
my current setup after the upgrades it went through...

D.

Is there any reason why you don't use the Emacs that comes with Cygwin?
Rebasing Cygwin won't help a bit if some of the GNUwin or MinGW
(depending on the build) librraies that Emacs is compiled with collide
in that same address space.

Re: [h-e-w] cygwin-64 2.3.1. bash fails when running under FSF emacs 24.5

[Dominique de Waleffe]

There never was any reason to do as I have so far always been able to
run a version of Emacs compiled without cygwin without any blocking
issue but still running cygwin tools under emacs (and that has been a
case for a very long time!).  I have no religious opinion on this but
I don't see why I should add a dependency that, in "principle" should
not be needed.

The previous build of Emacs on the gnu site was already build with
mingw and afaik it works. It is just that the current combination does
not, in my case. I have no clue as to which version of mingw is
involved in those two emacs builds. But maybe you're onto something
there... Do you have any suggestion as how to validate your
hypothesis?

My goal is not to complain and just have a quick work around, I'd
rather report the issue and if possible help in resolving the issue...
I see that my download has finished... I'll setup this vm and try what
I can with it

Regards,

D.

I'd say this is somehow related to 64-bit Cygwin programs being run by
32-bit native Windows programs.  The version which works for you is a
64-bit executable, those that don't are 32-bit.

Maybe there are compatibility issues vis-à-vis 64-bit Cygwin.

These are Cygwin errors, which I hope Cygwin folks will be able to
interpret.  Perhaps the stack dump trace produced by this will help
them even more, so I suggest to post its contents.
