The size calculation done in len_extops() (called by insn_size()) for
EOT_DB_RESERVE (i.e. uninitialized storage "?" token) does not take
into account the element size (e->elem), thus calculating a wrong
size for any Dx larger than DB (DW, DQ, etc).
The bug is silent, but it makes NASM error out if a "Dx ?" (larger
than DB) is followed by any label because the label offset gets
mismatched in the final code generation stage:
$ cat test.asm
[section .bss]
DW ?
x:
$ nasm test.asm
test.asm:3: error: label `x' changed during code generation [-w+error=label-redef-late]

NASM, the Netwide Assembler
Many many developers all over the net respect NASM for what it is: a widespread (thus netwide), portable (thus netwide!), very flexible and mature assembler tool with support for many output formats (thus netwide!!).
Now we have good news for you: NASM is licensed under the "simplified" (2-clause) BSD license. This means its development is open to even wider society of programmers wishing to improve their lovely assembler.
Visit our nasm.us website for more details.
With best regards, the NASM crew.
