6.7.4-4 Windows x64 access violation while reading TIFF

[keox]

Hello,

Decoding the attached tiff images causes access violation from time to time. The ImageMagick library was built from source using VisualStudio 2010 will all updates.

Tiff images:

Here is the relevant part of the stack:

We'll take a look and report back. We've had problems in the past extracting the EXIF profile in TIFF. We may need to add an option to only extract the EXIF profile if an option is set, e.g. -define tiff:exif-properties=true.

Hi,

Do you have any news on this bug? Or a time estimation at least?

Thank you.
