------- Comment #4 from dberlin at gcc dot gnu dot org  2005-10-02 02:05 -------
Subject: Bug 22254

I actually came across a case recently where we do call it for 
PARM_DECL's.
I'll try to find it again

------- Comment #5 from dnovillo at gcc dot gnu dot org  2006-03-10 15:45 -------

The two pointers are assigned the same SMT.  Is this still a problem?

Dereferenced pointers

D.1541, UID 1541, int *, symbol memory tag: SMT.5
D.1542, UID 1542, int *, symbol memory tag: SMT.5

Or do you need to analyze g1 and g2?

> By "These formals" i mean g1 and g2

Thanks for the clarification: I clearly remember "someone" at GCCSummit puzzled
by the spelling checker marking "formal" as error ;)
