From: Tietew Date: 2006-08-11T14:24:03+09:00 Subject: [ruby-dev:29254] SEGV in ruby_re_compile_pattern Tietewです。 REXMLで比較的大きなXHTMLをパースしていると、たまにSEGVします。同 じ文章をパースしても起こるときと起こらないときがあり、不安定です。 微妙にバージョンが古いのですがとりあえず報告しておきます。 /usr/local/lib/ruby/1.8/rexml/text.rb:324: [BUG] Segmentation fault ruby 1.8.5 (2006-07-28) [i686-linux] (gdb) bt #0 0xb7db983b in raise () from /lib/tls/libc.so.6 #1
