#277 pixeltype changed in GetBuffer method

While loading a JPEG-compressed image the pixel type of a gdcmBitmap object changes (from 12 bits allocated to 16).
See line gdcmBitmap.cxx:415.
This is done in a const method, Bitmap::TryJPEGCodec(), called by Bitmap::GetBuffer().

This behaviour raises problems when GDCM is used by ITK: in itkGDCMImageIO.cxx an image gets read, then GetBuffer
is called and afterwards the pixel type is checked for changes (only in Debug mode).

I've got a customer with a DICOM series that hits this assert with ITK 4.13.

And the image appears doubled as in bug #325.

Do I assume correctly that the issue still exists in git master?

Mathieu, did you fix this? Seems I no longer reproduce using ITK master from the other day!
