Assemble the following two files to ELF objects: --- CUT f1.asm --- struc s1 .s11 resd 1 endstruc bits 32 section .stext exec t1: mov eax,[sbss_1] section .data section .bss resb 0x2000 global sbss_1 sbss_1 resd 1 --- END CUT f1.asm --- --- CUT f2.asm --- bits 32 section .text extern sbss_1 t2: mov eax,[sbss_1] --- END CUT f2.asm --- ...and link them to an executable. You will find that the address used for sbss_1 in f1.o is out by 0x2000 (or whatever you change the 0x2000 to in f1.asm above), for example: Script started on Sun Mar 3 02:20:35 2002 [EMAIL PROTECTED]:~/proj/t$ nasm -felf f1.asm [EMAIL PROTECTED]:~/proj/t$ nasm -felf f2.asm [EMAIL PROTECTED]:~/proj/t$ ld -o test f1.o f2.o ld: warning: cannot find entry symbol _start; defaulting to 08048080 [EMAIL PROTECTED]:~/proj/t$ objdump --disassemble test test: file format elf32-i386 Disassembly of section .text: 08048080 <t2>: 8048080: a1 8c b0 04 08 mov 0x804b08c,%eax ^ Disassembly of section .stext: 08048085 <t1>: 8048085: a1 8c d0 04 08 mov 0x804d08c,%eax ^ [EMAIL PROTECTED]:~/proj/t$ Furthermore, this bug occurs ONLY when a structure is defined at the top of f1.asm as above - if the structure is defined after section .stext is introduced, or the structure is not defined at all then the bug does not appear (although adding section .other before the structure does not stop the bug from occuring). Neither does it appear if we rename the section .stext to .text. The "section .data" line is also required to trigger the bug. I am afraid I have absolutely no idea what is causing this. It could well be a bug in ld (binutils 2.11.93.0.2-2), I don't know. -- System Information Debian Release: 3.0 Architecture: i386 Kernel: Linux cronos 2.4.18 #2 Thu Feb 28 21:55:26 GMT 2002 i686 Locale: LANG=C, LC_CTYPE=C Versions of packages nasm depends on: ii libc6 2.2.4-7 GNU C Library: Shared libraries an --------------------------------------- Received: (at 136525-close) by bugs.debian.org; 17 Apr 2002 11:38:23 +0000 >From [EMAIL PROTECTED] Wed Apr 17 06:38:23 2002 Return-path: <[EMAIL PROTECTED]> Received: from auric.debian.org [206.246.226.45] (mail) by master.debian.org with esmtp (Exim 3.12 1 (Debian)) id 16xnlX-00048z-00; Wed, 17 Apr 2002 06:38:23 -0500 Received: from katie by auric.debian.org with local (Exim 3.12 1 (Debian)) id 16xnfW-0005re-00; Wed, 17 Apr 2002 07:32:10 -0400 From: Christian Kesselheim <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] X-Katie: $Revision: 1.13 $ Subject: Bug#136525: fixed in nasm 0.98.28bf-1 Message-Id: <[EMAIL PROTECTED]> Sender: Archive Administrator <[EMAIL PROTECTED]> Date: Wed, 17 Apr 2002 07:32:10 -0400 Delivered-To: [EMAIL PROTECTED] We believe that the bug you reported is fixed in the latest version of nasm, which is due to be installed in the Debian FTP archive: nasm_0.98.28bf-1.diff.gz to pool/main/n/nasm/nasm_0.98.28bf-1.diff.gz nasm_0.98.28bf-1.dsc to pool/main/n/nasm/nasm_0.98.28bf-1.dsc nasm_0.98.28bf-1_i386.deb to pool/main/n/nasm/nasm_0.98.28bf-1_i386.deb nasm_0.98.28bf.orig.tar.gz to pool/main/n/nasm/nasm_0.98.28bf.orig.tar.gz A summary of the changes between this version and the previous one is attached.
