Boost1.54/regex doesn't throw exception on invalid pattern (regression)

[xnox@…]

#include <boost/regex.hpp>

main () {
	boost::regex("{notclosed");
}

Above code is essentially part of source-highlight test-suite. Above code is expected to throw boost::regex_error exception. And it did so up-to boost 1.53, with boost 1.54 it no longer throws that.

Expected output

$ ./a.out 
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::regex_error> >'
  what():  Invalid content of repeat range.  The error occurred while parsing the regular expression: '{>>>HERE>>>notclosed'.
Aborted (core dumped)
$ echo $?
134

Actual with boost1.54

$ ./a.out
$ echo $?
0

I guess it's because PERL in the default parser? in that case above is bugfix for ​https://svn.boost.org/trac/boost/ticket/8569

Never mind, this is not a bug, but rather a bugfix.

Adjusted test:

#include <boost/regex.hpp>

main () {
	boost::regex("{notclosed");
}

fails with all boosts correctly. Please close.

• correction

#include <boost/regex.hpp>

main () {
	boost::regex("[");
}

fails everywhere.
