FIX: GPF/UAE with Huge Array Size as Multiple of 64K Bytes

• Microsoft Visual Basic Standard and Professional Editions for Windows, version 2.0

SYMPTOMS

A general protection (GP) fault or Unrecoverable Application Error (UAE) may result when you define a huge array using DIM, REDIM, or GLOBAL and specify a size that's a multiple of 64K.

CAUSE

Huge arrays that cause a GP fault or UAE are a(n), where n is 4094 + 4095*i for i = 1 to 7 (assuming 16-byte element sizes). The problem occurs when the array plus its overhead fills a space of 128K and each increment of 64K exactly.

WORKAROUND

To work around the problem, add or subtract one element in the array.

STATUS

Microsoft has confirmed this to be a bug in Microsoft Visual Basic version 2.0 for Windows. This bug was corrected in Microsoft Visual Basic version 3.0 for Windows.

MORE INFORMATION
