Milestone:  Boost 1.39.0               |   Component:  regex      
  Version:  Boost 1.35.0               |    Severity:  Problem

---------------------------------------+------------------------------------
 I have a code that matches URI with a pattern using regex_match. This code
 fails sometimes, mostly when a lot of threads (50 and above) call this
 function simultaneously. I have read the boost:regex is thread-safe. Here
 is the stack

 [1] __lwp_kill(0x0, 0x6, 0x0, 0x6, 0xffbffeff, 0x0), at 0xff0caa58

 [2] raise(0x6, 0x0, 0x0, 0x6, 0x82bf8, 0x6), at 0xff065a5c

 [3] abort(0xf88f9e78, 0x2, 0x0, 0xfcb78, 0xff1413d8, 0x1), at 0xff04194c

 [4] __assert(0x1f7544, 0x1f7557, 0x1ed, 0x1c00, 0xfc894, 0x1b41ac), at
 0xff041b88

 [5]
 boost::basic_regex<char,boost::regex_traits<char,boost::cpp_regex_traits<char>
 > >::get_traits(0x4e4130, 0xffff0000, 0x0, 0x1f75ed, 0x0, 0x1f7400), at
 0xc77e0

 [6] boost::regex_match<const char*,std::allocator<boost::sub_match<const
 char*> >,char,boost::regex_traits<char,boost::cpp_regex_traits<char> >
 >(0x2212e30, 0x2212e6e, 0xf88fa368, 0x4e4130, 0x0, 0x7ffffc00), at 0xc7664

 [7] URL::parseUrl(0xf88fa4cc, 0x1fc21c, 0x2212e30, 0x56e500, 0xf88fa4d0,
 0xf88fa368), at 0xcef5c
 Thanks
