OK, fixed in 8.8, this will be in 8.8.2. Thank you very much for reporting this dumbness!

Hello @Kyle-Kyle ,

I see this too with:

$ echo UEYgNiAgMCAjRgEAGwAAAAMACzxa//8AABQAgP//ABEIAPsBIBvtIooA+vA= | base64 -d > x
$ vipsheader x

It looks like it's trying to read the ppm header and failing. Thanks for reporting this!

libvips compiled using the --without-ppm flag is not affected by this.
