Description:The following call file causes asterisk 1.6.0.6 to segfault.  NB. $NUMBER isn't really a variable.  I've just sanitized.  Platform is 32bit Centos 5.2, but I think that's irrelevant.

Channel: SIP/provider/$NUMBER
RetryTime: 5
MaxRetries: 5
Context: default
Application: RetryDial
Data: please-wait|5|5|SIP/provider/$NUMBER|60
Account: testAccount

Using commas works as expected, but a segfault is an over reaction! :)

Patch uploaded and ready for testing.  In the future, please enable DONT_OPTIMIZE when reporting with a backtrace, as it makes figuring out where the problem actually lies much easier.
