Segmentation Fault during Vips::Image.new_from_array() #285
Description
Describe the bug
Seg fault when running Vips::Image.new_from_array() against an array generated with Vips::Image::to_a
To Reproduce
I have tried this with a few image inputs and they are all the same. This is the simplest program to cause the seg fault:
$ ruby -e "require 'vips'; Vips::Image.new_from_array(Vips::Image.new_from_file('image.png').to_a)"
System
Windows 10 running Ubuntu 2004.2020.424.0
$ ruby -v
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux-gnu]
$ gem list | grep vips
ruby-vips (2.0.17)
$ gem list | grep ffi
ffi (1.15.0)
Output
$ ruby -e "require 'vips'; Vips::Image.new_from_array(Vips::Image.new_from_file('image.png').to_a)"
