[Ironpython-users] crash on Win8 64bit at IronPython expression evaluation

Keith, you are absolutely right. Not the background thread causes this error.

I tried to make a simpler application that throws the same exception but I was not able to do it.

Then I tried to debug it in Visual Studio 2010 but if I debug then the error does not appears.

I cannot post the full application source code so we will give up it, because it is not reproduceable.

As a last word I would like to note that we have two windows 8 64 bit computer and on both pc the software crashes.



Regards,



Zoltan

Are you able to narrow down the problem to a small script that reproduces it?

 

The code pointed to in that call stack doesn’t really have many ways of failing in that way (null reference). The most likely thing is that DefaultContext.DefaultPythonContext is not being set. But I think that is done for you when the scripting runtime is initialized.

 

How are you creating the script runtime?

 

Running from a background thread shouldn’t have any bearing on it, unless this were a race issue. And since the crash is happening in a static ctor, that pretty much rules out thread races.

Hi,

 

We are using IronPython and Windows 8 long time, but now we have an exception that only occurs on windows 8 64 bit. (We did not test on Windows 8 32 bit but tested on Windows 7 32/64 bit where it is ok.)

The application crashes at the first ironpython expression evaluating.

I think it is important to note that we are using IronPython from a background thread. We cannot debug it on windows 8. If this exception is similar to you please help us.

 

Thanks,

Zoltan
