Re: [Boost-users] using boost.regex on submatches.

str() returns a std::string by *value* Thus, the two iterators point into different string objects.

I get a segmentation fault if I run this - sometimes with a memory exhausted notice.

If I replace the iterator line

boost::sregex_iterator it(sm[1].str().begin(), sm[1].str().end(), handles);

with

const string& hs(sm[1].str()); boost::sregex_iterator it(hs.begin(), hs.end(), handles);

then everything seems to work.

What's going on here? Is there a simpler way of achieving this?

Now you only get one string object. In Christ, Steven Watanabe
