Summary: NASM crashes when building x64 .obj file

Initial Comment:
I have been trying to convert TrueCrypt to use solely NASM - a fresh download uses both NASM and YASM. However, NASM crashes when assembling the Aes_x64.asm file.

Steps to reproduce:
1 - download the attached file
2 - alter YASM instructions to NASM equivalents; change line  719 from:
    lea tptr,[enc_tab wrt rip]
to:
    lea tptr,[rel enc_tab]
and line 833 from:
    lea tptr,[dec_tab wrt rip]
to:
    lea tptr,[rel dec_tab]
3 - execute nasm.exe -Xvc -f win64 -d DLL_EXPORT -o Aes_x64.obj Aes_x64.asm. NASM will crash

To avoid the crash, comment out line 675:
    export  aes_encrypt
or remove -d DLL_EXPORT from the command line.

NASM version - 2.07
OS - WinXP SP3

Thanks,
Barry

Nevermind.  I was able to reproduce this, and this is, indeed, explicitly
fixed by checkin 7ad24562dccca867d9ba591ac7dd242456003c5b.  So this is, of
course, a real bug, but it has been fixed already.

I guess it is time for 2.08-rc1 soon...

Message:
The current version doesn't appear to have this problem.  You may want to
try the latest release version and/or the latest snapshot from
http://www.nasm.us/.

Message:
This does not seem to happen with the latest snapshot build, could you
please confirm that?

That may just be hiding the error, though -- I don't see anything in the
history which is likely to be a fix for this problem...
