I see. gld 2.21 does handle it though, so I suppose gold should as well
to be a drop-in replacement?

I've had a look:
(gdb) up
#2 0x085c959d in gold::Symbol_table::sized_write_globals<32, false>
(this=0x8046d9c, sympool=0x8046bf4, dynpool=0x8046c38, symtab_xindex=0x0,
dynsym_xindex=0x0, of=0x897f3d0) at
/vol/gnu/src/binutils/binutils-hg/gold/symtab.cc:2850
(gdb) p ps
$1 = (unsigned char *) 0xfe51e9b4 <Address 0xfe51e9b4 out of bounds>
(gdb) p psyms
$2 = (unsigned char *) 0xfe51e874 <Address 0xfe51e874 out of bounds>
So it seems the bad value is from symtab.cc:2706:
psyms = of->get_output_view(this->offset_, oview_size);
gold::Output_file::get_output_view (this=0x897f3d0, start=383092, size=2752) at
/vol/gnu/src/binutils/binutils-hg/gold/output.h:4105
(gdb) p this->base_
$5 = (unsigned char *) 0xfe4c1000 <Address 0xfe4c1000 out of bounds>
(gdb) p start
$6 = 383092
(gdb) p this->base_ + start
$7 = (unsigned char *) 0xfe51e874 <Address 0xfe51e874 out of bounds>
The bad value for base_ is already in layout.cc
(Write_symbols_task::run), but I cannot readily see how to trace it back
further up.
