BUG: LSTRCMP and LSTRCMPI May Fail With Non-US Regional Settings

 Last reviewed: February 16, 1998
Article ID: Q178529
The information in this article applies to:
  • Microsoft Windows Software Development Kit (SDK) on the following platform: 

        - Windows 95

SYMPTOMS

Under the following conditions, the LSTRCMP and LSTRCMPI string-comparison APIs may erroneously report that two strings fail to compare:

  1. Windows 95 is configured for a Regional Setting other than "English (United States)."

  2. One of the strings is located in a 16-bit discardable code segment which has been discarded.

CAUSE

If the regional setting is anything other than English (United States), the string-compare call is thunked to 32-bit string-compare functions in Kernel32. The thunking code does not force a segment reload if the segment containing a string that is supposed to be compared has been discarded.

RESOLUTION

It may be possible to work around this problem using one of the following methods:

  • If a segment contains a string that is going to be compared with LSTRCMP or LSTRCMPI, do not mark that segment as discardable.
  • Touch the string in some way to force the segment to be reloaded if it is discarded before calling LSTRCMP or LSTRCMPI.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.
