Hi: I did not get an answer to this before, so I'll post again. I just did a cvs get and compiled 1.7.3 on Solaris: uname -a SunOS juno 5.8 Generic_108528-14 sun4u sparc SUNW,Ultra-5_10 When running irb, I get the following error: irb /home/jfn/myruby173/lib/ruby/1.7/sparc-solaris2.8/nkf.so: [BUG] Segmentation fault ruby 1.7.3 (2002-12-04) [sparc-solaris2.8] Abort Is this a known problem? -- Jim Freeze
