any update on that? is there any workaround? I am trying to parse from ISO 8601
date/time format to C++11 time_points and relied on std::get_time to do the
parsing work. Any ideas on how to accomplish that by other means? Thanks

I just realized I can use operating system functionality to achieve the same
goal. Please ignore my question and thanks for the quick follow up. Looking
forward to gcc 4.9.0

[Bug libstdc++/68058] New: _GLIBCXX_BEGIN_NAMESPACE_VERSION breaks regex

[dmorilha at gmail dot com]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68058

Bug ID: 68058
   Summary: _GLIBCXX_BEGIN_NAMESPACE_VERSION breaks regex
   Product: gcc
   Version: 5.2.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: libstdc++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: dmorilha at gmail dot com
  Target Milestone: ---

when compiling libstdc++ with --enable-symvers=gnu-versioned-namespace
std::regex complaining about private data members trying to be accessed outside
the class:

22:55:46 /home/y/include/c++/4.9.2/bits/regex.h:796:30: error:
‘std::__7::basic_regex::_AutomatonPtr
std::__7::basic_regex::_M_automaton’ is protected
22:55:46_AutomatonPtr  _M_automaton;

I believe the bug is related with the __detail namespace[1] and friend
classes[2] as it lacks the NAMESPACE_VERSION expansion. This happens in other
lines and I believe it extends to hashmap as well. Turning data members public
"fixes" the compilation problem.
