As soon as I call png_create_read_struct, the application will imediately hang and start using up all available CPU power. This happens with both libpng10 and libpng12. This is the call we make: png_structp png_ptr = png_create_read_struct (PNG_LIBPNG_VER_STRING, (png_voidp)0, 0, 0); Anybody who knows anything about it, or knows what more information I should provide?
