[Bug c/38945] No warning when using uninitialized variable

[manu at gcc dot gnu dot org]

------- Comment #1 from manu at gcc dot gnu dot org  2009-01-24 16:05 -------
I am almost sure that this is CCP again assuming that the undefined value is
the same as the constant assigned, hence x++ is converted to 0++. This can be
checked using -fdump-tree-all-all-lineno.

If so, a duplicate of bug 18501.
