 /* PR c/4389
    This testcase failed because host_integerp (x, 0) was returning
-   1 even for constants bigger than 2^31.  */
+   1 even for constants bigger than 2^31.  It fails under under hpux
+   without -mdisable-indexing because the pointer x - 1 is used as
+   the base address of an indexed load.  Because the struct A is not
+   actually allocated, x - 1 lies in the text segment and this causes
+   the wrong space register to be selected for the load.  */
