Description
When a series of fuzzed .otf font files are loaded and passed to AddApplicationFontFromData, the application crashes with an access violation.
Will attach the fuzzed font files and a simple main.cpp that shows the problem
The .otf files need to be placed into the exe location or the path in the main function needs to point to the folder containing the files.
