Per Anonymous's lead ...
I researched gcc Embedded Functions:
https://gcc.gnu.org/onlinedocs/gcc/Nested-Functions.html
Apparently, his description of how the functions work, AKA they can only
be used when the external parent function is executing, is correct.
Sad, really. As all the other compilers don't treat embedded functions
this way.
To test this theory, I moved the parent function .. JSON .. so that it
just enclosed the malloc expressions. The code compiled correctly, and
executed correctly.
/me sighs.
Here is a discussion on the merits of Internal vs External encapsulation.

As for me, I was using it for scope resolution. Helping to make the
code more OO, as well as help avoid naming conflicts between various C
modules.
It should not matter if the functions are internal or external, though,
internal functions should not have an expectation to internal variables,
as they do in an OO environment. And, I think the use of labels to
create the OO effect in C is a waste typing. Plus it breaks with C's
conventions of no GOTO statements.
