10204	boost::lockfree:queue: g++ -fgnu-tm and -O1/2/3 flag not working	philipp.schoppe@…	timblechmann	"The combination of g++ -fgnu-tm and optimization flags do not work
when when using boost::lockfree::queue.


{{{
#include <boost/lockfree/queue.hpp> 

int main () { 

     boost::lockfree::queue<int> lfqueue; 
     lfqueue.push(234); 

     return 0; 
} 
}}}

Compiling it using
{{{
g++ -std=c++11 -g -Wall -Werror -lboost_system -fgnu-tm
}}}
works. Adding -O1 / -O2 / -O3 leads to the error:
