Comment (by marshall):

 [ Marshall posting for Peter ]

 This issue arose as of
 [http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=197248 GCC SVN
 commit 197248] which implements [http://www.open-

 std.org/jtc1/sc22/wg21/docs/papers/2013/n3582.html N3582].  It occurs
 because the
 [http://gcc.gnu.org/viewcvs/gcc/trunk/gcc/cp/parser.c?r1=197248&r2=197247&pathrev=197248

 change on line 4109] preserves parentheses at the front end (with that
 change reverted, gcc works correctly).

 This is now [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59681 PR
 C++/59681].  The fix in GCC is not trivial, so I've just made
 [https://github.com/boostorg/regex/pull/1 pull #1] so the trivial fix for
 boost (remove the parens) can be applied.
