+ * objfiles.h (SECT_OFF_DATA, SECT_OFF_TEXT, SECT_OFF_BSS,

+ * gdb-stabs.h (SECT_OFF_DATA, SECT_OFF_TEXT, SECT_OFF_BSS,

+ * objfiles.c (allocate_objfile): Initialize
+ sect_index_{text,data,bss,rodata} to -1, for error detection.
+
+ * symfile.c (default_symfile_offsets): Initialize
+ sect_index_{text,data,bss,rodata} from bfd information.
+ * xcoffread.c (xcoff_symfile_offsets): Ditto.
+ * somread.c (som_symfile_offsets): Initialize
