Subject: [ruby-dev:46769] [ruby-trunk - Bug #7590] parallel test-all で test_settracefunc が cfp consistency error


Issue #7590 has been updated by kosaki (Motohiro KOSAKI).


うちのx86_64 linuxだと以下のように vm_call_cfunc - cfp consistency error でrb_bugして、その延長でsegv.
ところで、一般論としてcfp consistency errorが起きてる時に ruby level backtraceが採取できる可能性はないんじゃないですかね。

-- C level backtrace information -------------------------------------------

Some worker was crashed. It seems ruby interpreter's bug
or, a bug of test/unit/parallel.rb. try again without -j
option.
