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

• Microsoft Win32 Software Development Kit (SDK)
  on the following platforms: Win95

SYMPTOMS

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

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



• 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. If the segment containing a string to be compared has been discarded, the thunking code does not force a segment reload.

RESOLUTION

You may be able to work around this problem using one of the following methods:

• If a segment contains a string to be compared with LSTRCMP or LSTRCMPI, do not mark that segment as discardable.



• If a segment is discarded before calling LSTRCMP or LSTRCMPI, touch the string in some way to force the segment to be reloaded.

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.
