Hello Gaius,

Yes, managed to create a test case that recreates the problem this
morning.  It consists of the definition and implementation module
below.

inserttok1.def:

DEFINITION MODULE inserttok1;

(* Just filling the token buffer up *)
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR VAR
VAR VAR VAR VAR VAR VAR VAR VAR VAR

(* Intentional misspelled VAR keyword *)
PROCEDURE whatever( VAT s: ARRAY OF CHAR) : CARDINAL;

END inserttok1.

inserttok1.mod:

IMPLEMENTATION MODULE inserttok1;

(* Hit this problem in a definition module *)

END inserttok1.

$gm2 -g -c inserttok1.mod
gm2: Internal error: Segmentation fault (program cc1gm2)
