Description :
Adding a new global variable as follows :
let typ = (TInt(IInt,[])); and loc = {Lexing.dummy_pos with Lexing.pos_lnum=1; Lexing.pos_fname=file} in let var = Cil.makeGlobalVar ~logic:false ~generated:false se_var_name typ; and iv = {init=Some(Cil.makeZeroInit ~loc:(loc,loc) typ)} in var.vdecl <- (loc,loc); var.vdescr <- Some("side_effect variable for FDC analysis"); try Globals.Vars.add var iv; with Globals.Vars.AlreadyExists (,)-> Printf.printf "Error adding Global %s" var.vname
makes Frma-C crash, raising a Not Found exception, with the following command :
frama-c-gui -testGlobal ../VAL/LOT/testBug.c where "-testGlobal" is our plug-in adding a global variable.
There is no crash using the command "frama-c", the problem only appears using the interface (with "frama-c-gui").
Additional Information :
I do not know is the cause is related to a lack of information at the moment of the creation of the global variable.
The full backtrace is:
