Public bug reported:
Binary package hint: nasm
I'm using nasm-0.98.38-1.2 on Dapper on amd64. Here is a small test
program to show a problem in ndisasm:
; test.asm:
bits 32
org 0xefb58
call 0xef980
Assemble with:
nasm -o test.bin test.asm
Then, disassemble with ndisasm:
ndisasm -b 32 -i -o 0xefb58 test.bin
Result:
000EFB58 E823FEFFFF call 0x1000ef980
Expected result:
000EFB58 E823FEFFFF call 0xef980
This seems to happen with relative calls to lower memory addresses (negative
values).
IIRC, this works on i386 architectures, so I suppose that the ndisasm
code expects an overflow of a variable at 0x100000000, but that is not
true on 64-bit architectures.
** Affects: nasm (Ubuntu)
Importance: Untriaged
Status: Unconfirmed

ndisasm sometimes outputs addresses plus 0x100000000 on amd64
