This works OK:
#!/usr/bin/ruby
require 'tk'
class TkVariable
def to_m
"%.2f" % [self.to_i.abs/100.0]
end
end
puts TkVariable.new(12345).to_m
-> 123.45
But when I add the -w option to the first line, I get:
/usr/local/lib/ruby/1.8/tk.rb:2313: warning: redefine encoding=
/usr/local/lib/ruby/1.8/tk.rb:2316: warning: redefine encoding
123.45
Segmentation fault
and this takes 45 seconds.
What’s wrong?

I cannot cause SEGV on my Linux box.
Probably, we need more information to solve your trouble.

I tried the profiler:
#!/usr/bin/ruby -w
require ‘profiler’
require 'tk'
class TkVariable
def to_m
"%.2f" % [self.to_i.abs/100.0]
end
end
Profiler__::start_profile
begin
puts TkVariable.new(12345).to_m
rescue
Profiler__::stop_profile
Profiler__::print_profile($stdout)
end
but then the problem is gone.
I also tried -rdebug, but then I first get, as I always do when using
tk.rb, a Runtime Error: can’t unset “v00000”: no such variable, and then
when I continue, the problem is gone again:
$ ruby -rdebug t
Debug.rb
Emacs support available.

Oh, I’m sorry.
SEGV trouble on Ruby/Tk depends on tcltklib.so.
To check the reason, information of your environment
(OS, nativethread suuport, library verion, and so on) are required.
If you can, please report the followings.
Anyway, the follwoing wraning and error are expecetd.
Those have no problem, but the exception may cause SEGV.
However, I think such troubles on exception are fixed on ruby 1.8.3
or later. If no case of troubles is escaped notice.

Thank you for your report.
I think that depends on the finalize operation of a Tk interpreter
when Ruby is exiting.
But now, I have no time to fix the problem.
If you can, please comment out all part of ip_finalize(ip) in
tcltklib.c and try to use it.
Probably, it causes some problems when the running Ruby releases
Tk IP objects.
However, on your case, you may be able to avoid the SEGV trouble.

I suppose it is the latest, as it comes with ruby-1.8.4?

I’d try to fix the problem. The diff of ruby_1_8 branch is
http://www.ruby-lang.org/cgi-bin/cvsweb.cgi/ruby/ext/tk/tcltklib.c.diff?r1=1.40.2.5;r2=1.40.2.6;only_with_tag=ruby_1_8.
Could you try it?

Sorry for being so late with my reaction. Had other troubles and
also had to find out how to get 1.8.4 from cvs.It does not seem to work. What I did was:
cvs -z4 -d :pserver:[email protected]:/src checkout -r ruby_1_8 ruby
patch -p0 <patch→ patching file ruby/ext/tk/tcltklib.c
Reversed (or previously applied) patch detected! Assume -R? [n] y
‘ruby_1_8’ branch on CVS is already applied the patch.
You rolled back tcltklib.c.
If you can try the latest version on CVS,
please try it without the patch.

patch -p0 <patch
cd ruby
autoconf
./configure
make
./ruby …/warntest
./ruby -w …/warntest
where warntest contained:
require ‘tk’
class TkVariable
def to_m
“%.2f” % [self.to_i.abs/100.0]
end
end
puts TkVariable.new(12345).to_m
The first run on warntest worked fine.
But the ruby -w …/warntest gave the old problem: very heavy system load
ending in a segmentation fault.

Ah, I see… I thought that could not be the case because, before
doing the patch, I tried my test and it went wrong.
I’m very sorry that I’m bothering you.
But I want to ask you one more try.
At Apr. 6 01:04:47, I committed patches of tk.rb and tk/variable.rb
to remove some warnings.
Please check on the latest version of those.
Possibly, the result helps me to fix the SEGV trouble.

I replaced tcltklib with the original and tried without patching:
