Re: [X2Go-Dev] Windows nightly crashes

2020-05-20 Thread Melroy van den Berg
Hi Uli,

Try to debug the code using the debugger? Adding print lines is not the way to 
do it.

I hope somebody can say how to re-compile the code with debug symbols and if 
gdb is good enough?

Kind regards,
Melroy van den Berg

"the debugger" is something I don't know. I am not developing software
on Windows (I am not even using Windows if I can avoid it). Therefore
I also have no development environment to do anything. On Linux I can
install gdb and attach to any program but I simply do not know what's
possible on Windows. I have read about minidumps and VS tools you need
to debug. I have nothing like that. Is a minidump created
automatically? Where can I find it?

I have also tried to exchange the libssh by an older version but it is
extremely difficult to find a compiled libssh.dll file for reasons I
am not sure about. Seems like shared libs with a stable API is
something that is not common in the Windows world...

Not me, sorry...

[X2Go-Dev] Windows nightly crashes

Hi,

both x2goclient for windows 4.1.2.2-20200213 and
https://code.x2go.org/releases/binary-win32/x2goclient/heuler/mingw32-4.8/qt-4.8/x2goclient-4.1.2.3-2020.05.20-a1a2f62-setup.exe
are crashing during connection establishment when using a proxy
(output from the debug build):

and then x2go completely vanishes.

Any ideas how to debug this further?
