Hui Zhang <hzhang.online@outlook.com> and I successfully built Slicer 4.3.1-2014-10-02 r23735 on a 64-bit Windows 8.1 system using Qt 4.8.6 and Visual Studio 2012. There were no errors during the build process. We cannot load and display DICOM images but cannot save them.

Results from Hui Zhang's debugging:
The result of node->GetName() seems to be "1: Unknown",

if (snode->GetFileName() && node->GetName())
{

QFileInfo existingInfo(snode->GetFileName());

QFileInfo newInfo(existingInfo.absoluteDir(), QString(node->GetName() + QString(".") + existingInfo.completeSuffix()));

// Only reset the file name if the user has set the name explicitly (that is,

// if the name isn't the default created by qSlicerVolumesIOOptionsWidget::setFileNames

// TODO: this logic relies on the GUI so we should consider moving it into MRML proper

// with a way for storage nodes to generate their default node names from a given filename

if (existingInfo.completeBaseName() != QString(node->GetName()))

{

snode->SetFileName(newInfo.absoluteFilePath().toLatin1()); <<<< Exception here

node->StorableModified();

}

}

}
