> Occasionally I get "failed to extend from %d to %d" messages output.  In this case I performed a CLI "core show channel CBRec/xxx" and got the message for the native formats on the channel.
> The culprit is the ast_str variable is declared too small to list all formats.  An audit is need for the uses of ast_str_alloca() when used to hold the format capabilities string.  Currently ast_str_alloca(64) is used throughout the code base for this particular case.  The 64 needs to be replaced with a define to eliminate the magic number and the number needs to be increased to 256 when all codecs are allowed.
