<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">During dialplan execution in pbx_extension_helper(), the contexts global read lock is used prevent changes to the dialplan. This patch puts a copy of exten->data on the stack so that can be referenced safely during variable substitution (expression evaluation) even if another thread is reloading dialplan and has deleted ast_exten.
