Eric Howey updated ASTERISK-24194:
----------------------------------

    Description: 
When calling an outside lua library, such as lua-sql-mysql, the library fails to load. After searching on this issue, it appears to be resolved once before in ASTERISK-17279, but after looking through the changelog for 11.11.0, it was reverted back to its original setting in r416581-416668. This change triggers the same issue that was first found in ASTERISK-17279. Simply replacing AST_MODFLAG_DEFAULT with  AST_MODFLAG_GLOBAL_SYMBOLS resolves the issue at hand.
