I've been seeing this happen occasionally when starting irb1.8 as well.
After some experimentation, I see that irb1.8 works (at least minimally)
when I'm in an ssh session, but not when in a local X terminal window.
The relevant difference in these cases is that the ssh session has a
soft limit on the stack size, but it's unlimited in the local session.
Setting the limit locally allows it to work there as well. Example
shell session:
18)frell$ dpkg-architecture -qDEB_HOST_ARCH
powerpc
19)frell$ ulimit -s
unlimited
20)frell$ irb1.8
/usr/lib/ruby/1.8/irb/context.rb:77:in `attr_accessor': stack level too deep
(SystemStackError)
from /usr/lib/ruby/1.8/irb/context.rb:77
from /usr/lib/ruby/1.8/irb.rb:14:in `require'
from /usr/lib/ruby/1.8/irb.rb:14
from /usr/bin/irb1.8:10:in `require'
from /usr/bin/irb1.8:10
zsh: exit 1 irb1.8
21)frell$ ulimit -s 8192
22)frell$ irb1.8
irb(main):001:0>
23)frell$ echo $?
0
I may have time over the weekend to look for the actual cause of this
bug, but maybe this will provide enough of a pointer for someone with a
knowledge of ruby's memory management code to find the bug. And if not,
it may provide a work around until the bug is fixed.
