[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=211268#comment-211268 ] 

Matt Jordan commented on ASTERISK-22755:
----------------------------------------

This is not a bug, as there is no memory leak on that code path. {{mailbox_full}} is allocated using Asterisk's wrapper around alloca, which allocates memory on the stack, not the heap.

{noformat}
	mailbox_full = ast_alloca(strlen(box) + strlen(context) + 1);
{noformat}

More information on alloca can be found here: http://man7.org/linux/man-pages/man3/alloca.3.html
