incorrect checksum for freed object about tuneup_js

[alexvollmer]

It looks like a problem with Ruby. What version are you running and is it one that came with OS X or one you installed separately?

I appreciate your quick reply, Alex!
tunesup works fine with iOS 7., I just upgrade the OS and Xcode SDK to iOS8., I didn't remember I install Ruby, but I did install COCOAPODS this morning as well by using "sudo gem install cocoapods", not sure is cocoapods did something or not
which version of Ruby should I use?

[yezilife]

actually I ended up getting the latest tuneup js by clone from git hub directly but not through cocoapods

I believe this is not the new tuneup script issue, the same error happens if I switch back to old tuneup script, interesting thing is, if I keep trying RunTestCase.sh, it will pass the error after a few try, but eventually it will fail at later steps (I think it's Instruments path)

[yezilife]

even I run >ruby -v
ruby(24391,0x7fff76253300) malloc: *** error for object 0x100801a08: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

Are you running the stock Ruby, or one you installed yourself?

[yezilife]

i am not sure, i didn't do any configuration, should I use which one? and how can I specify?

I fixed the ruby issue by installing Ruby 2.1.4, new issues shows up:
