[Bug ld/19623] regression: erroneous relocation for symbols in absolute section (vma == 0)
https://sourceware.org/bugzilla/show_bug.cgi?id=19623 --- Comment #6 from winter-...@bfw-online.de --- Judging from the correspondence regarding the fix for DJGPP [1] it seems that DJGPP and SCO differ in their behaviour when it comes to relocating symbols in absolute sections (== those with vma=0). While DJGPP was broken when relocation was turned off, SCO worked. Currently, it is the other way round. Some info on djgpp [2] and SCO (albeit ELF, see SHN_ABS) [3].

It doesn't work for x32 which has has 64-bit arch address and 32-bit
pointer.
+ segment_type * seg;
+ bfd_vma max = ((bfd_vma) 1) << bfd_arch_bits_per_address
(link_info.output_bfd);

%V\n"),
+seg->name, seg->value, max - 1);

Umm, are you sure ? Could you create a test case for me to check please ?
