[Bug c/19771] VLA deallocation

[steven at gcc dot gnu dot org]

------- Comment #3 from steven at gcc dot gnu dot org  2009-03-29 22:36 -------
Created an attachment (id=17557)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=17557&action=view)
Always create a new BIND_EXPR for VLA decls

I tried to make use of scopes: If a label is defined in a parent scope, start a
new BIND_EXPR.  This did not work.

So the attached patch takes the brute-force approach.  When optimizing, this
_should_ not hurt, but we get two __builtin_stack_restore calls now. 
Apparently Jakub's PR23848 fix doesn't work for our case.

Anyway, this patch does, of course, make the test case of comment #0 run.
