            Bug ID: 3392391
           Summary: Incorrect warning: dword data exceeds bounds
           Product: NASM
           Version: unspecified
          Hardware: All
                OS: All
            Status: OPEN
          Severity: normal
          Priority: Medium
         Component: Assembler
          Assignee: nobody at nasm.us
          Reporter: henrik at gramner.com
                CC: gorcunov at gmail.com, hpa at zytor.com, nasm-bugs at nasm.us

An overflow warning is produced when using an address consisting of a 32-bit
register with a negative offset below -128 (e.g. it doesn't fit in a signed
byte).

The correct output (with a 4-byte offset) is produced, so it's just the warning
that's wrong.

Minimal test case:

lea eax, [eax-129]
