#7539 new Bugs

including spirit multi_pass and info header files caused compile error

Reported by: zhuo.qiang@… Owned by: Joel de Guzman
Milestone: To Be Determined Component: spirit
Version: Boost 1.52.0 Severity: Showstopper
Keywords: spirit, c++11, multi_pass Cc:

Description

It seems the 2 header files

  • boost/spirit/include/support_info.hpp
  • boost/spirit/include/support_multi_pass.hpp

are not getting along very well using clang and its libc++ under c++11

If the 2 files are included in the same complie unit (either directly or indirectly) like following:

#include <boost/spirit/include/support_info.hpp>
#include <boost/spirit/include/support_multi_pass.hpp>

It will fail the clang with flag '-std=c++11', '-stdlib=libc++'

clang++ -o test.o -c -std=c++11 -stdlib=libc++ -I/Users/qiang/Projects/boost_1_51_0 test.cpp

Attachment is the complete error message.

Reproduced in

  • Apple clang version 4.1 (tags/Apple/clang-421.11.65) (based on LLVM 3.1svn)
  • Target: x86_64-apple-darwin12.2.0
  • With C++ 11 turn on: "-std=c++11 -stdlib=libc++" , the 2 flags must be turned on at the same time to reproduce this bug
  • Boost 1.51 and Boost Trunk rev.81030

I'm getting the same failure with Oracle Solaris Studio C++ 12.4 compiler. Works fine for -std=c++03 and fails with 'incomplete type "boost::spirit::info"' for -std=c++11.

At least for Studio C++ it looks like a bug in compiler when handling alignment_of<recursive_wrapper<incomplete_type>> where implementation of alignment_of goes through the alignment_of_hack path.

Workaround found: -DBOOST_ALIGNMENT_OF=__alignof
