Crash on invalid expression in Release

[GoogleCodeExporter]

What steps will reproduce the problem?

The following c++ code illustrates the problem

ParserX p;
p.SetExpr(_T("1 == ??.??.???? ??:00:00.000")); // crashes muParser on 
evaluation in Release only
Value result = p.Eval();

What is the expected output? What do you see instead?
Instead of exception with error, the evaluation crashes muParserX

What version of the product are you using? On what operating system?

2.3.1 version of muParserX
OS: Windows 7 Professional (Visual Studio 2010)
