--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- We run into 2949 /* Canonicalize the PT uid of all aliases to the ultimate target. 2950 ??? Hopefully the set of aliases can't change in a way that 2951 changes the ultimate alias target. */ 2952 gcc_assert ((! DECL_PT_UID_SET_P (node->decl) 2953 || DECL_PT_UID (node->decl) == DECL_UID (node->decl)) 2954 && (! DECL_PT_UID_SET_P (t) 2955 || DECL_PT_UID (t) == DECL_UID (node->decl))); -fno-ipa-icf fixes it.
