[Bug tree-optimization/39355] [4.4 Regression] Revision 144529: ICE due to missing or incorrectly relocated DECL_VALUE_EXPR in PCH header for PARM_DECL

["danglin at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #48 from danglin at gcc dot gnu dot org  2009-03-24 16:31 -------
On i686-apple-darwin9, this doesn't fail because DECL_HAS_VALUE_EXPR_P (loc)
is not set:
