run.exe fails to start XWin in Windows 8.1

run.exe fails to start XWin in Windows 8.1

[jaakov jaakov]

Dear cygwin maintainers:

While executing the command "Xwin Server" from Windows 8.1, the server won't start. Apparently, the executed command is

C:\cygwin64\bin\run.exe --quote /usr/bin/bash.exe -l -c "cd; /usr/bin/startxwin"

The file C:\cygwin64\run.exe.stackdump is produced. Instead I expect, however, an X server process and an xterm window.

On the other hand, starting first "Cygwin64 terminal" does create a text console shell, and running 

startxwin      &

from this shell does give me an X server process and an xterm window.

A complete removal of the C:\cygwin64 directory and reinstalling did not help. Afterwards, reinstalling xinit did not help.

This issue persists for a few months already. Last year, XWin started without problems.

Any help?

(I tried to add attachments, but somehow the e-mails do not appear on the cygwin mailing list site.)

Best,

Jaakov

Unfortunately, the stackdump in your previous report [1] didn't quite 
contain enough information to investigate this problem.  I've made a 
small improvement in how the stackdumps are made [2] since then, so if 
you can upgrade and provide the stackdump file, perhaps we can discover 
why this crash is happening.

Great, I'll test it as soon as possible!

Thanks for following up on this.

But I'm sorry, there's nothing to go on there.

Is it possible for you to upload the output of stracing that run command 
somewhere?

RE: run.exe fails to start XWin in Windows 8.1

[Bravery, Gavin S]

You review (and possible upload) the output from this directory:
/var/log/xwin
You could at least then confirm the xwin application is running, and starting (even if it then crashes)...

I had issues after recent upgrades (probably over a year ago) because of what I had in my local .startxwin...
I only discovered it by looking at these xwin logs.
