mtoa crash on CExtensionAttrHelper

[froszu]

I am getting maya crash with CExtensionAttrHelper in NodeInitializer method.

What can I do to debug this situation ?

Following are details...

Code:

// voxelizer_mtoa_translator derives from CShapeTranslator
void voxelizer_mtoa_translator::NodeInitializer(CAbTranslator context)
{
	CExtensionAttrHelper helper(context.maya, "Voxelizer"); // Voxelizer is a name of my mayaShapeNode
	//CShapeTranslator::MakeCommonAttributes(helper); //uncommenting this line crashes maya
}

This is under windows 10, build with MSVC 2017 Community edition, v15.5.3

MtoA 2.1.0

PasteBin for better code formatting

I think the reason is MSVC version I used...

I build minimal working code with MSVC v11 2012 and it works fine.

With MSVC v15 2017 it crashes.

Which means I'm in trouble now, because I'm not sure OpenVDB want's to build with older compiler.

What MSVC version is supported for MtoA 2.1.0 ?

[froszu]

It seems the highest version that does not crash is MSVC v12 2013

However to use OpenVDB I need at least MSVC v14 2015.

Any ideas how to handle this?
