             Bug #: 33059
           Summary: Visual Basic 6 shows overflow error with arithmetic
                    expressions
           Product: Wine
           Version: 1.5.24
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: german_ant_82 at yahoo.com
    Classification: Unclassified
   Regression SHA1: Visual Basic 6 shows overflow errors with arithmetic
                    expressions that has results greather than 32767


When running a program or on the immediate window, Visual Basic 6 shows an
overflow error with arithmetic expression that has results greather than 32767.

    Dim a As Long
    a = 32768      <-- This doesn't cause any error
    a = 32767 + 1  <-- This one causes overflow error

The error message dialog shows:
    Run-time error '6':
    Overflow

This is not a normal behavior. Here, the arithmetic expressions are calculated
with 16 bits binary numbers with a range from -32768 to 32767, but Visual Basic
6 is a 32 bits environment with integer expressions with a range from
-4294967296 to 4294967295.
