Bug #9167: Segmentation fault in cleanup

ruby -v: ruby 1.9.3p448 (2013-06-27 revision 41675) [i386-ruby 1.9.3p448 (2013-06-27 revision 41675) [i386-freebsd9]freebsd9]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


I don't know whether it is the interpreters fault or mine.
This is what I do:

  - Subclassing StandardError in C
  - Encapsulating some data into it using Data_Make_Struct
  - Raising this exception
  - Not catching it by "rescue"

If I catch it by "rescue", everything is fine. If I don't, the
finalizer crashes with a segmentation fault.

I made a gem out of it containting the full example and a little
bit more description. See the attached file.

This gem contains a build dependency, so you probably prefer to
untar it and compile it on the command line by "cc". This is what
I have to do here:

  $ cc -c -DHAVE_HEADER_RUBY_RUBY_H -I/usr/local/include/ruby-1.9 -I/usr/local/include/ruby-1.9/i386-freebsd9 -fPIC -o dataerr.o dataerr.c
  $ cc --shared -o dataerr.so dataerr.o
  $ ruby -r ./dataerr -e 'begin ; raise_it! ; rescue ; end'
  -> Return code 0
  $ ruby -r ./dataerr -e 'raise_it!' 
  -> Segmentation fault
