That's true.

1) Do never call the Frama-C parser yourself. Just call Ast.get (more 
generally, one of the functions of the module Ast).

2) You don't give the whole context of your plug-in, but this exception 
is usually raised when your code is executed too early. See Frama-C 
Plug-in Development Guide, Section 4.13 "Initialization Steps". Quoting:
"As a general rule, plug-in routines must never be executed at link 
time. Any useful code, be it for registration, configuration or C-code 
analysis, should be registered as function hooks to be executed at a 
proper time during the Frama-C boot process.
