------------------------------------------

             Summary: Function SHARED randomly broken
                 Key: ASTERISK-26627
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26627
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Functions/General
    Affects Versions: 14.2.0
         Environment: Linux 4.8.0-27-generic #29-Ubuntu SMP Thu Oct 20 21:03:13 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
            Reporter: Jonathan Harris
         Attachments: debug_log_123456.txt

For the following code:
{code}
[svtest1]
exten => s,1,Answer()
    same => n,Verbose(1,Answered channel:${CHANNEL})
    same => n,Dial(Local/s at svtest2,,g)
    same => n,Verbose(1,***In channel:${CHANNEL} sharedVar: ${SHARED(sharedVar,Local/s at svtest2)} )
    same => n,Hangup()  
    
[svtest2]
exten => s,1,NoOp()
    same => n,Set(SHARED(sharedVar,Local/s at svtest2)="I have been set in svtest2")
    same => n,Verbose(1,***In channel:${CHANNEL} sharedVar: ${SHARED(sharedVar,Local/s at svtest2)})
    same => n,Answer() 
    same => n,Hangup()   
{code}

I get the following output, dialled 4 times from console, 4 times from a normal PJSIP softphone:

Of the 8 attempts. in only 3 instances the variable survives the journey back to the parent channel, and seemingly randomly, too.
Am I using it incorrectly?
