[boost] regex crashes under release buid

I recently made the switch from visual studio 2005 to visual studio 
2008.  I have a project that uses boost regular expressions as shown in 
the following fragment:

bool StringCompDesc::is_valid_input(char const *s)
{
    bool rtn = strlen(s) <= max_len;
    if(rtn && validate_pattern.length())
    {
       boost::regex ex(validate_pattern.c_str());
       boost::cmatch what;
            
       rtn = boost::regex_match(s,what,ex);
    }
    return rtn;
} // is_valid_input

When this method is invoked with a value of "192.168.4.230" and a 
validate_pattern value of "^([0-9]{1,3})?(\.[0-9]{1,3}){0,3}$" under the 
release build, the program crashes.  The stack trace shows that 
match_results<>::set_size() winds up invoking 
_invalid_parameter_noinfo().  I have seen this with both versions 1.33.1 
and 1.34.1.

It would appear that visual studio 2008 is not a recognised build 
environment for boost but, despite the warning messages emitted in the 
boost headers, it has appeared to work until now.  If anyone is aware of 
a way to work around this problem, I would appreciate their advice.
