Summary:                    Segmentation Fault when Calling app Voicemail after
Blind Transfer
Description: 
So I have a macro called macro-staff which is used to handle extension to
extension dialing.  The macro works perfectly for everything except BLIND
call transfers.  In features.conf the blind transfer key is set to '##' so
if you press '##' during a call Asterisk will prompt you for the extension
you wish to blind transfer the call to.

Here is the situation.  The transfer actually works, so when you press
'#http://bugs.digium.com/view.php?id=100#' as an example the call is properly
transfered to extension 100. 
The problem is if extensions 100 does not answer, macro-staff tries to send
the call into Voicemail(100) and as soon as that happens Asterisk does a
Segmentation fault.

Interestingly enough if you do a transfer from the phone, using the
Transfer button on the acutal phone, and extension 100 does not answer, and
VoiceMail(100) is called from inside macro-staff, there is NO segmentation
fault.  It only does a segmentation fault when it reaches voicemail from a
blind transfer using the '##'.

macro-staff runs no matter what, so if you press '##' to do a blind
transfer, macro-staff is called (nested) just the same as it would be if
you transfer the call using the transfer button on the phone.  So either
way there is a nested call to macro-staff, but only one when using the
'##', (blind transfer) does a segmentation fault happen.
