Is there any reason why they are not declared with .data directive? Or this is missing? This is just a bug, as is formatting mail for 220-column terminals. It is missing in the reference i386 version which has a .data directive before some other variables that don't exist on amd64. Apparently, these variables only work because the text section is not write protected. Write protection of the text section was lost long ago on i386. intrnames and eintrnames are also in the text section. Bruce
