[cdt-patch] proposed fix for 1.2 branch

[John Camelon <jcamelon@xxxxxxxxxx>]

This is the same (simple) fix as was applied last night on the HEAD branch 
for https://bugs.eclipse.org/bugs/show_bug.cgi?id=50821
The consequences of not applying it is that the scanner's error handling 
strategy causes an out-of-memory error to happen on a unterminated 
character literal when CModelBuilder kicks in (i.e. on save or reconcile).
