Re: [ruby-gnome2-devel-en] seeing GC-related crashes in 3.0.7, I think

[<jc...@gm...>]

I've made an example that shows the problem, but it is quite large :-( sorry.

This is a binding for the vips image processing library.

The libvips packaged for ubuntu is missing the typelib, unfortunately,
so you need to build from source:

https://github.com/jcupitt/libvips

You need:

./bootstrap.sh
./configure --prefix=/home/john/vips
make
make install

Then add vips to your library path and to GI_TYPELIB_PATH.

Then install this branch of this gem:

https://github.com/jcupitt/ruby-vips8/tree/gc-segv

so:

bundle install
rake build
gem install pkg/ruby-vips8-0.1.0.gem

Then run:

$ ./example/example3.rb
loop 0 ...
loop 1 ...
loop 2 ...
loop 3 ...
loop 4 ...
loop 5 ...
loop 6 ...
loop 7 ...
/home/john/packages/gems/gems/gobject-introspection-3.0.7/lib/gobject-introspection/callable-info.rb:31:
[BUG] rb_gc_mark(): 0x00000001ff1878 is T_NONE
ruby 2.1.2p95 (2014-05-08) [x86_64-linux-gnu]

Please let me know if you have problems setting this up, perhaps I can
make it smaller.
