I am very interested, but when I attempted to link your code I got the following error:

Undefined symbols:
  "boost::stack_trace::write_symbols(void* const*, int, std::basic_ostream<char, std::char_traits<char> >&)", referenced from:
      boost::backtrace::trace(std::basic_ostream<char, std::char_traits<char> >&) const in libfl_scheduler-1.a(scheduler.cpp.o)

In the code you provided I saw backtrace.hpp and backtrace.cpp, neither one provides an implementation for boost::track_trace::write_symbols, what am I missing?
