[ITK-users] bug in imageIOFactory

[Scott Pfeifer]

Hi all,
 I have found what seems to be a bug in IOFactory which seems to be a
threading issue.  I do not have a fix for it but I have a small program
which reproduces the issue.  I will attach the files.

The fix I have for the situation is to either put a mutex around all
itkIamgeFileReader::Update()'s of assign the ioObject if I already know
what sort of image I am dealing with.
You will have to change the file names to some mhd files you have, if you
need me to provide some I can do that.

to make the problem go away here just uncomment line 24 or 32 in
ItkTestThreadSupport.cpp

I am running Itk 4.5.2 and boost 1.55

If I can be of any assistance I would be happy to hel p- my stack trace
looks like this



H5MM_xfree()
H5E_preintf_stack()
H5E_clear_starck()
