            Bug ID: 3392571
           Summary: intra-section call doesn't cause error or warning
           Product: NASM
           Version: 2.14.xx
          Hardware: All
                OS: All
            Status: OPEN
          Severity: severe
          Priority: Medium
         Component: Assembler
          Assignee: nobody at nasm.us

     Obtained from: From OS distribution

When calling from one (multi-section bin format) section to another, with
differing vstart values (not one following the other), the call is not flagged
by an error or warning.
