Hi all,
I found a problem that examples\Plugins\PropertyWidgets result in crash for paraview release x64 version.
Below is my steps to reproduce the problem.
- Compile ParaView with CMAKE and vs2015 for release x64 version. All features are OK.
- Compile sample located in examples\Plugins\PropertyWidgets for release x64 version.
- Startup compiled paraview, then loading the ExamplesPropertyWidgets.dll, paraview crashing. (Both paraview and ExamplesPropertyWidgets.dll are release version.)
- It is confusing that debug version works fine when loading debug ExamplesPropertyWidgets.dll.
My environment is as follows:
- ParaView version: 5.5.2 and 5.6.0
- Qt version: 5.9.6
- CMake version: 3.13.0
- Compiler: VS2015
regards.

Hi, Thank you for your reply.

These plugins are based on the same architecture as the example plugin.
What errors are you having ?

For the **Debug** version of ParaView, select the **Debug** version of PropertyWidgets via Tools-\>Manage Plugins, and the loading is **successful** ;
For the **Release** version of ParaView, select the **Release** version of PropertyWidgets via Tools-\>Manage Plugins, and ParaView **crashes** and exits.
THanks!

I have not been able to reproduce your issue. Release plugin on release ParaView works great.
