Description:If you currently use IAX2 encryption in chan_iax2 it will result in a segfault.

workspace = alloca(*datalen + 32);

Last I tried I increased the datalen + 33 and it didn't segfault but packet decrypt will fail.

adding encryption=aes128 to your IAX entry on both ends will be enough to recreate this issue.
