Review request for Asterisk Developers and Matt Jordan.
Bugs: AST-1179 and AST-1246
https://issues.asterisk.org/jira/browse/AST-1179
https://issues.asterisk.org/jira/browse/AST-1246
Repository: Asterisk
Description
-------
During dialplan execution in pbx_extension_helper(), the contexts global read
lock is used prevent changes to the dialplan. This patch adds a lock between
that point and until after the extension previously found is no longer being
referenced -- after variable substitution, but before app execution. This new
lock prevents the extension's allocation from being released by module reload
when it is still being used in an expression evaluation.
