Hi,

Using SHLWAPI in native mode with IE6 ends like this :
$ wine --winver winme IEXPLORE.EXE
[....]
Unhandled exception: page fault on read access to
0x00000001 in 32-bit code (0x4081749c).
In 32-bit mode.
Symbol h_errno is invalid
0x4081749c (PathIsUNCServerShareA+0x44 [path.c:1308]
in libshlwapi.so): cmpb	$0x5c,0x0(%esi)
1308 if (lpszPath[0]=='\\' && lpszPath[1]=='\\')	

regs are like this :Wine-dbg>info regs

Using last CVS code.

Looks as if we need something like this to cater for IE6
(I have nothing directly to gain by this.  My browser of choice is
wget :-)


ChangeLog:
	dlls/shlwapi/path.c:
	Lawson Whitney <lawson_whitney@juno.com>
	Protect PathIsUNCServerShare from null lpszPath.
