[asterisk-bugs] [JIRA] (ASTERISK-19612) Asterisk crash with compiler flag LOW_MEMORY

[Olle Johansson (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-19612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=206087#comment-206087 ] 

Olle Johansson commented on ASTERISK-19612:
-------------------------------------------

Looking at the code I see that we allocate 256 structures for the payload handling, and in most call only use a handful. There has to be a way to make this more optimized to save memory. We should possibly only allocate this for calls that actually change the default payload format and then only allocate the changes.

> When using compiler flag LOW_MEMORY, asterisk-10 crashes as soon as an SIP call is made. I discovered that initially with asterisk-10.2.1, but same with 10.3.0, and I also tried 10.0.0-beta1. Verified on 2 completely different environments: Mandriva-2010.2 32 bits, and Fedora 16 64 bits. I'm running Asterisk on a Alix board, so low memory is preferred.
