[asterisk-bugs] [JIRA] (ASTERISK-27238) Yet another crash freeing a frame that's already been freed

[Richard Kenner (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=238489#comment-238489 ] 

Richard Kenner commented on ASTERISK-27238:
-------------------------------------------

I may well have created a leak:

Exiting with the following memory not freed:
   3079377 bytes (3079377 in caches) in 8447 allocations. frame.c ast_frdup()

Somebody who understands this code and how memory allocation of frames is done needs to look at this.
