Problem using YAML/SYCK on Solaris 8

[andi]

I'm using ruby 1.8.2 (2004-06-28) [sparc-solaris2.8] and yaml/syck
in a daemon script to write alive messages every 10 seconds.
Sooner or later the loop/thread/script ends with one of the following
error messages:

....
9179
9180
9181
/usr/local/lib/ruby/1.8/yaml.rb:340: [BUG] Segmentation fault
ruby 1.8.2 (2004-06-28) [sparc-solaris2.8]

Abort (core dumped)

OR

....

Here is the simplified source code ...
------------------------
require 'yaml'

i = 0
loop{
"HelloWorld".to_yaml
i+=1
STDERR.puts i
}
------------------------

uname -a
SunOS tb-sun-1 5.8 Generic_108528-12 sun4u sparc SUNW,Sun-Blade-1000

gcc -v

On Linux there is no problem ;-)


Any suggestions or hints??

Probably a problem in syck_emitter_new()

bonus and ignore_id must be affected *after* the call to
Data_Wrap_Struct() because if the GC run when Data_Wrap_Struct() is called
it can remove emitter->bonus

emitter->bonus was GC'ed

Understood. Fixed in CVS and Ruby 1.8 branch.

Andi, can you try again for me? Wonderful.

I think instance initialization should be in #initialize,
apart from the allocator.

It works!
Thanks a lot to Guy and _why.
