Hello,

The commit 985c965eca140470d87912cebd923cd27a6d892c breaks booting an
iso image under qemu. Isolinux gives the output:

ISOLINUX 3.53 0x4718b656

and locks.

Any way I could get a copy of said iso image?

Also, what version of NASM are you using? Please make sure you're
running 0.98.39 or 0.99.04 or later.

It's quite big, but the attached image also dies. It's like the
original, but without the kernel and initrd.

0.98.39, but I'll try a newer version anyway.

$ rpm -q nasm
nasm-0.98.39-5.fc7
$ nasm -v
NASM version 0.98.39 compiled on Apr 13 2007

Also, qemu is version:
QEMU PC emulator version 0.9.0, Copyright (c) 2003-2007 Fabrice Bellard

0.98.39 should work. It is what I consider baseline at this point.

Oh yes, could you also send me the files isolinux.lst, isolinux.lsr, and
isolinux.map produced by your compile?

Thanks,

Err, no. I didn't find any isolinux.lst, .lsr and .map, only pxelinux.

$ ls *.lst *.lsr *.map
copybs.lst pxelinux.lsr pxelinux.lst pxelinux.map

Anyway, after battling with nasm (configure:4869: error: NASM requires
ANSI C header files to compile), the error is still the same.

nasm $ git describe
nasm-0.99.05-8-gf3eea3d

If you have more tests for me to do, I'll be glad to oblige, but I have
a bus to catch now.

I did a make spotless and rebuild, now I get those files.

The files are in:
<http://ftp.gil.di.uminho.pt/pub/users/strange/isolinux-data.tgz>

(Warning: the tarball decompresses all files to cwd.)

isolinux.bin still locks, but isolinux-debug.bin continues and tries to
boot the kernel (that doesn't exist in the image I sent).

Hi there,

This turned out to be a very serious bug. I have fixed it; the fix is
in 3.53-pre3.

Thanks for your report!
