AVR gdb misinterprets what function I am in

Hi,

I don=E2=80=99t know if this is the correct mailing list. I=E2=80=99m =
looking for help with avr-gdb.

I'm not sure if this is a dumb question! I'm debugging a firmware image =
I wrote, connecting to  simulator via target remote. When I do =
disassemble 0, I get the correct assembly for address 0x0000 on my image =
(it's an AVR program by the way). But, gdb seems to think it's in some =
random function that has nothing to do with the startup code=E2=80=A6

(gdb) disassemble 0x0000
Dump of assembler code for function =
_ZN5swift9RefCountsINS_21SideTableRefCountBitsEE11doDecrementILNS_13Perfor=
mDeinitE0EEEbm:
0x00000000 <+0>:    jmp    0x90    ;  0x90 <__init>
=E2=80=A6
(this is the start of program memory at 0x0000 on the AVR chip, the =
reset vector and interrupt vectors)


As a sanity check, using avr-objdump, that symbol is not defined as =
0x0000...=20
00001186  w    F .text	00000226 =
_ZN5swift9RefCountsINS_21SideTableRefCountBitsEE11doDecrementILNS_13Perfor=
mDeinitE0EEEbm

Why is gdb thinking the code at 0x0000 is in some other, random =
function? (It seems to change all the time, one random symbol after =
another, different each time I start a debugging session like this!)
