             Bug #: 14058
           Summary: Internal overflow error, on >128kB FLASH with no
                    relaxation
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
                CC: address@hidden
    Classification: Unclassified
            Target: avr


If there are gs()'d labels both below and above the 0x20000 boundary, during
linking without -relax an "internal overflow error" is thrown.

A simple minimum example is (filename y3a.S):
.text
.global   main
main:
  ret

.global K1
.org 0x100
.L1:
K1:
  nop
.global K2
.org 0x20002
.L2:
K2:
  nop

.section .progmem
.word gs(.L2)
.word gs(.L1) 

Using
"c:\Program Files\Atmel\AVRTools\WinAVR20100110\bin\avr-gcc" y3a.S -Os
-DF_CPU=14745600UL -mmcu=atmega2561 -Wa,-adhlns=y3a.lst
-Wl,-Map=y3a.map,--cref,--debug-stubs -o y3a.elf 

yields
Adding stub with destination 0x20108 to the hash table.
(Pre-Alloc run: 1)
Adding stub with destination 0x206 to the hash table.
(Pre-Alloc run: 1)
Allocating 1 entries in the AMT
Building one Stub. Address: 0x20110, Offset: 0x0
Final Stub section Size: 4
LD: Using jump stub (at 0x20000) with destination 0x2010c for reloc at address
0xcc.

error: out of range error 

Confirmed to persist on avr-ld v2.22 too.
