I am getting following crash in boost algorithm
stack trace is :

function used as foloows in the code :
boost::split(signals, name, boost::is_any_of("."), boost::token_compress_on);
template<typename Derived>
struct predicate_facade {};
In above code, i am getting can not access memory error in gdb for this pointer :
(gdb) p this Cannot access memory at address 0x7fffff3feff8
But it worked fine in small code (tried on ideone): https://www.ideone.com/jnB037 Please help me out.
Thanks in advance
