Can you provide a Minimal, Complete, and Verifiable Example?

Because your log mentions:

• phone_decode.c with at least 284 lines of code
• PocketSphinxProcessor.m with at least 213 lines of code
• PocketSphinxManager.m with at least 1256 lines of code

And none of those files are part of pocketsphinx repository.

Note that you are showing us a piece of code very similar to https://github.com/cmusphinx/pocketsphinx/blob/master/test/unit/test_state_align.c#L24, but with an fprintf added, which means you're on some fork of some sort. Here, in pocketsphinx repository, the "Test bad alignment" is done on "<s> go forward ten meters </s>" which is too small to cause any memory issue: can you provide the dictionary that has caused your memory allocation error?
