[Bug 1228201] Re: g++ doesn't compile simple code, using thread header

[Come Raczy]

On trusty the problem is still present when linking against any of the boost library (tried both 1.54.0 or 1.55.0) - the workaround (-Wl,--no-as-needed) still works though. This is what I get using the 'thread.cpp' provided above:

craczy at vb:/tmp$ g++ thread.cpp -pthread -std=c++11 -o thread
craczy at vb:/tmp$ ./thread 
1307674368000
355687428096000
craczy at vb:/tmp$ g++ thread.cpp -pthread -std=c++11 -o thread -lboost_filesystem
craczy at vb:/tmp$ ./thread 
terminate called after throwing an instance of 'std::system_error'
  what():  Enable multithreading to use std::thread: Operation not permitted
Aborted (core dumped)

Title:
  g++ doesn't compile simple code, using thread header

Status in “gcc-defaults” package in Ubuntu:
  Fix Released

Bug description:
  Bug is only for 13.10. I'm learning c++ and I tried to write a simple code using std::thread (code is in attachment). I found info, that the code won't build without -pthread/-lpthread g++ option. I build code with every position of this flags and with std=c++11/std=c++0x, but I've got the same error:
  shkiper at server:~/C++$ g++ thread.cpp -pthread -std=c++11 -o thread
  shkiper at server:~/C++$ ./thread
  terminate called after throwing an instance of 'std::system_error'
    what():  Enable multithreading to use std::thread: Operation not permitted
  Аварийный останов (сделан дамп памяти)
  shkiper at server:~/C++$
  I tryed to build this code on live cd -  same error.
  It bullds and works on ubuntu <13.10.
  I think, g++ doesn't links pthread lib:
