            Bug ID: 19582
           Summary: We decide a variable is undefined too early
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: MC
          Assignee: unassignedbugs at nondot.org
          Reporter: rafael.espindola at gmail.com

    Classification: Unclassified

We reject

--------------------
a:
    .section foo
    c = b
b:
    .long a - c
-------------------

gas accepts it, which seems more in line with most other behaviour in the
assembler (evaluating expression at the end).
