Serious trouble on PPC with Ruby 1.8.6


#1

Hello fine folks of ruby-talk!

I am taking some serious damage with the fresh ruby 1.8.6 after
updating from 1.8.4

All the usual rituals were executed including flushing the /usr/local/
lib.ruby hierarchy.
I rebuilt ruby a few times.

When running make-test-all I get:

/ruby-1.8.6/lib/drb/drb.rb:589: [BUG] Segmentation fault
ruby 1.8.6 (2007-03-13) [powerpc-darwin8.9.0]

/ruby-1.8.6/lib/rexml/parsers/streamparser.rb:17: [BUG] Segmentation
fault
ruby 1.8.6 (2007-03-13) [powerpc-darwin8.9.0]

and …
make: *** [test-all] Abort trap

The rest is all green - dots dots dots

Any attempt to use the freshly polished ruby raises issues. For
instance, most of rdoc runs end with:

Installing RDoc documentation for camping-1.5.180…
/usr/local/lib/ruby/1.8/rdoc/parsers/parse_rb.rb:1273: [BUG]
Segmentation fault
ruby 1.8.6 (2007-03-13) [powerpc-darwin8.9.0]

This happened to me on about 4 gems already.

When I try to do the gem install something, I get a different
segfault in a different place altogether:

digi:/ruby-1.8.6 julik$ sudo gem install rails
/usr/local/lib/ruby/site_ruby/1.8/rubygems/version.rb:136: [BUG]
Segmentation fault
ruby 1.8.6 (2007-03-13) [powerpc-darwin8.9.0]

On the second try it does give me the usual “do you want to install
activesupport” message

Even a seemingly innocent gem list fails:

digi:/ruby-1.8.6 julik$ gem list -r

*** REMOTE GEMS ***
Bulk updating Gem source index for: http://gems.rubyforge.org
/usr/local/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:322: [BUG]
Segmentation fault
ruby 1.8.6 (2007-03-13) [powerpc-darwin8.9.0]

IRB works fine, so does ruby -v and friends

Works for some gems, does not work for others. Basically I haven’t
been getting that many segfaults in a year of using ruby.

gcc version 4.0.0 20041026 (Apple Computer, Inc. build 4061), OS X
10.4.9

Could someone give me a clue what is rotten? Black magic failed, I am
surely no wizard.

Can you provide the output from:

% gdb ./miniruby
gdb> r ./runruby.rb --extout=.ext – “./test/runner.rb” --basedir="./
test" --runner=console
… go boom …
gdb> bt

d’oh
turned out this had to do with some remaning binaries in /usr/local/bin
after flushing my whole /usr/local/bin|lib|share down the drain I
finally can reinstall ruby and gems
pronto

if only imagick was not such a PITA

and sorry for disturbing

Ah, cool. No worries.

Depending on what you want to do, you might want to check out
image_science. :slight_smile:

hello guys,
i’m experiencing exactly the same behavior as described in the mail
before.
since there was no solution on the thread i wanted to ask what could
be the problem here:

(gdb) r ./runruby.rb --extout=.ext – “./test/runner.rb” --basedir="./
test" --runner=console
Starting program: /Users/z3cko/Desktop/compile/ruby-1.8.6/miniruby
./runruby.rb --extout=.ext – “./test/runner.rb” --basedir="./ test"
–runner=console
Reading symbols for shared libraries … done

Program received signal SIGTRAP, Trace/breakpoint trap.
0x8fe01010 in __dyld__dyld_start ()
(gdb)

i am wondering if the problem could be related to a blog entry i found:
http://crafterm.net/blog/articles/2006/11/24/segmentation-faults-with-ruby-1-8-4-in-fink-10-4-tree-with-gcc-4

i am on an i386 machine, osx 10.4.9, gcc version 4.0.1 (Apple
Computer, Inc. build 5367). trying to build an universal ruby binary.

thanks for the help,
