BUG: LSTRCMP and LSTRCMPI Fails with Non-US Regional Settings (178529)


The information in this article applies to:

  • Microsoft Platform Software Development Kit (SDK) 1.0, when used with:
    • the operating system: Microsoft Windows 95
This article was previously published under Q178529

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.
