-
-Segmentation Faults and `std::terminate` calls sometimes happen in programs. Programmers usually wish to get as much information as possible on such incidents, so having a stacktrace will significantly improve debugging and fixing.
-
-`std::terminate` calls `std::abort`, so we need to capture stack traces on Segmentation Faults and Abort signals.

-[warning Writing a signal handler requires high attention! Only a few system calls allowed in signal handlers, so there's no cross platform way to print a stacktrace without a risk of deadlocking. The only way to deal with the problem - [*dump raw stacktrace into file/socket and parse it on program restart].]

-Let's write a handler to safely dump stacktrace:

+[section Handle terminates]
+
+`std::terminate` calls sometimes happen in programs. Programmers usually wish to get as much information as possible on such incidents, so having a stacktrace significantly improves debugging and fixing.
+
+Here's how to write a terminate handler that dumps stacktrace:
+
+[getting_started_terminate_handlers]
+
+Here's how to register it:
+
+[getting_started_setup_terminate_handlers]
+
+Now we'll get the following output on `std::terminate` call:
+
+```
+Previous run crashed:
+ 0# my_terminate_handler(int) at ../example/terminate_handler.cpp:37
+ 1# __cxxabiv1::__terminate(void (*)()) at ../../../../src/libstdc++-v3/libsupc++/eh_terminate.cc:48
+ 2# 0x00007F3CE65E5901 in /usr/lib/x86_64-linux-gnu/libstdc++.so.6

+ 9# 0x0000000000402209
+```
+
+[warning There's a temptation to write a signal handler that prints the stacktrace on `SIGSEGV` or abort. Unfortunately, there's no cross platform way to do that without a risk of deadlocking. Not all the platforms provide means for even getting stacktrace in async signal safe way.
+
+Signal handler is often invoked on a separate stack and trash is returned on attempt to get a trace!
+
+Generic recommendation is to *avoid signal handlers! Use* platform specific ways to store and decode *core files*.
