Bug in boost::regex_match 1.33.0 Win64/cl1400 and Linux/gcc323
Hello, After upgrading from boost 1.32 to boost 1.33.0, we get an exception in boost::regex_match. The exception is std::runtime_error: Regular expression too big , and only under Win64/cl1400 and RHEL/gcc323 Changing the regex slightly sometimes avoids the exception... Attached a small example, which can be used to reproduce the exception. #include <boost/regex.hpp> int main(void) { boost::regex validValue = boost::regex("([x]{0,64})?"); boost::regex_match("T",validValue); return 0; } best regards Robert Lopuszanski -- 5 GB Mailbox, 50 FreeSMS http://www.gmx.net/de/go/promail +++ GMX - die erste Adresse f�r Mail, Message, More +++

Confirmed in 1.33.0, the issue has already been fixed in preparation of 1.33.1, but since that isn't available yet, one temporary fix would be to define BOOST_REGEX_RECURSIVE in boost/regex/user.hpp and rebuild everything. Otherwise grab a copy of current cvs for the "RC_1_33_0" branch. Hope this helps, John.

In addition to defining BOOST_REGEX_RECURSIVE in 1.33.0 I also had to apply the attached patch in order to compile Boost under Windows x64. Otherwise the compiler is unable to deduce the correct template parameter for std::min(). Best regards, Peter.

Doh! Yes, you're quite right, applied thanks. John.
