[asterisk-bugs] [JIRA] (ASTERISK-17386) [patch] res_config_ldap with malloc_debug produces munmap_chunk(): invalid pointer:

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-17386?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=204151#comment-204151 ] 

Matt Jordan commented on ASTERISK-17386:
----------------------------------------

So, looking at recent 1.8, the original patch is a bit out of date:
* Some of the *_calloc based calls have been replaced with string dups
* There are some additional *_realloc based calls later on

The attached patch I think gets all of the various memory allocations, such that the later deallocations via the LDAP library should succeed with MALLOC_DEBUG enabled.

Andrew - since you run with LDAP, can you confirm that this works?

> If malloc_debug is turned on, as soon as an ldap realtime peer attempts to register, wham.
> This occurs at the ldap_mods_free call at line 1338.
