# jeremy-rifkin/cpptrace

> Cpptrace is a simple, portable, and self-contained C++ stacktrace library supporting C++11 and greater on Linux, macOS, and Windows including MinGW and Cygwin environments. The goal: Make stack traces simple for once.

It is used in MaNGOS to print the stack trace on failure.
