           Summary: Bug in SearchPath when filename supplied but null
           Product: Wine
           Version: 1.1.35
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernel32
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: us at edmeades.me.uk

Debugging a private application shows that SearchPath on wine returns success
incorrectly when passed a filename which is a valid pointer but points to a
null character.

I have a standalone testcase for this which is trivial to put into the main
wine testsuite, and I have also confirmed that a simple check for [0]==0x00 in
SearchPathW in kernel32/path.c and setting last error of 87 (invalid parameter)
and returning 0 fixes the problem in my application.
