          Hardware: x86-64
                OS: Mac OS X

Sample script

A call to DateAdd function breaks VBScript.

Sample (testdateadd.vbs):

1> aDateFrom = Now
2> MsgBox "Now: " & aDateFrom
3> aDateFrom = DateAdd("h", 1, aDateFrom)
4> MsgBox "+1h: " & aDateFrom

$ wine wscript testdateadd.vbs

Line 2 shows MsgBox, but line 4 does not execute.

Errors (error.log):

0009:fixme:variant:get_date_format ignoring flags 10
0009:fixme:vbscript:Global_DateAdd 
0009:fixme:wscript:ActiveScriptSite_OnScriptError ()
