Status changed from Open to Closed It's already fixed. Check 2.2.1. ---------------------------------------- Bug #10966: Seg fault when param with default is followed by named param https://bugs.ruby-lang.org/issues/10966#change-51833 * Author: Greg Beech * Status: Closed * Priority: Normal * Assignee: Yukihiro Matsumoto * ruby -v: 2.2.0-p0 * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN ---------------------------------------- The last line of the following code sample causes a seg fault. This seems to be the case for any method where a hash is passed to a parameter with a default value, when the method also has a named parameter. ~~~ class Foo def self.seg_fault(a = {}, b: 0); end end Foo.seg_fault('x' => 'y') ~~~ The output of running this is below, and the crash report is attached. ~~~ bug.rb:5: [BUG] Segmentation fault at 0x00000000000010 ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14] -- Crash Report log information -------------------------------------------- See Crash Report log file under the one of following: * ~/Library/Logs/CrashReporter * /Library/Logs/CrashReporter * ~/Library/Logs/DiagnosticReports * /Library/Logs/DiagnosticReports for more details. -- Control frame information ----------------------------------------------- c:0002 p:0027 s:0006 E:0009c0 EVAL bug.rb:5 [FINISH] c:0001 p:0000 s:0002 E:001390 TOP [FINISH] -- Ruby level backtrace information ---------------------------------------- bug.rb:5:in `
