Follow-up Comment #1:

Tests done for fix:

simulavr started with:

src/simulavr -g -d atmega328 -f ~/Downloads/boot.elf

gdb sessions starts via ddd with:

ddd --debugger /opt/avr_5.2.0/bin/avr-gdb ~/Downloads/boot.elf

gdb session tested:

0x00000000 in ?? ()
(gdb) set $pc=0x7ff0
(gdb) 

assembly window output:

Dump of assembler code from 0x7ff0 to 0x80f0:
=> 0x00007ff0 <appStart+10>:    ijmp
   0x00007ff2 <appStart+12>:    .word   0xffff  ; ????
   0x00007ff4:  .word   0xffff  ; ????
   0x00007ff6:  .word   0xffff  ; ????
   0x00007ff8:  .word   0xffff  ; ????
   0x00007ffa:  .word   0xffff  ; ????
   0x00007ffc:  .word   0xffff  ; ????
   0x00007ffe <optiboot_version+0>:     cpc     r0, r18
   0x00008000:  Cannot access memory at address 0x8000

Result:
File was read from 0x7ff0 to 0x7fff with correct content, checked with
avr-objdump. Last two bytes comes from 

00007ffe <optiboot_version>:
    7ffe:       02 06           cpc     r0, r18

which is the same as displayed in gdb session.

Fix commit id is: 0c7c098cc52851b40063508db2718760f7e0823f
