辻本です。

以下のようにテストを実行すると、まれにTestSetTraceFuncの実行に失敗することがあります。

 $ make TESTS='-vq -j1 objspace/test_objspace.rb \
                       json/test_json_fixtures.rb \
                       json/test_json.rb \
                       xmlrpc/test_marshal.rb \
                       xmlrpc/test_features.rb \
                       uri/test_parser.rb \
                       uri/test_http.rb \
                       uri/test_ftp.rb \
                       uri/test_generic.rb \
                       io/console/test_io_console.rb \
                       rexml/test_stream.rb \
                       rexml/test_light.rb \
                       rexml/test_xpathtext.rb \
                       rexml/test_xpath_pred.rb \
                       rexml/test_rexml_issuezilla.rb \
                       ruby/test_case.rb \
                       ruby/test_hash.rb \
                       ruby/test_marshal.rb \
                       ruby/test_proc.rb \
                       ruby/test_yield.rb \
                       ruby/test_string.rb \
                       ruby/test_settracefunc.rb' test-all

失敗するケースは2つ確認していて、
1つめがRubyレベルで失敗するもの:

 TestSetTraceFunc#test_break = 0.00 s = .
 TestSetTraceFunc#test_c_call = 0.00 s = .
 TestSetTraceFunc#test_call = 0.00 s = .
 TestSetTraceFunc#test_class = 0.00 s = .
 TestSetTraceFunc#test_invalid_proc = 0.00 s = .
 TestSetTraceFunc#test_raise = 0.00 s = .
 TestSetTraceFunc#test_raise_in_trace = 0.00 s = .
 TestSetTraceFunc#test_remove_in_trace = 0.00 s = .
 TestSetTraceFunc#test_return = 0.00 s = .
 TestSetTraceFunc#test_return2 = 0.00 s = .
 /home/k_tsj/work/ruby/lib/test/unit/parallel.rb:40:in `rescue in block in _run_suite': undefined local variable or method `local_var' for #<Test::Unit::Worker:0x002aaaaaf8a5a0> (NameError)
         xyzzy:2:in `eval'
         xyzzy:2:in `block in trace_by_tracepoint'
         /home/k_tsj/work/ruby/lib/test/unit/parallel.rb:40:in `rescue in block in _run_suite'
         /home/k_tsj/work/ruby/lib/test/unit/parallel.rb:36:in `block in _run_suite'

2つめがSEGVを起こすものになります。

 TestSetTraceFunc#test_break = 0.00 s = .
 TestSetTraceFunc#test_c_call = 0.00 s = .
