+/* If you are reading this, you are probably doing so because this test case just failed. This might happen as it
+ * heavily depends on platform and compiler behavior. There are two likely causes why this could break:
+ *
+ *  - Your compiler found new ways to optimize the functions that are called to create a stack, even though we tried
+ *    to disable optimizations using #pragmas for some compilers. If you know a way to disable (more) optimizations for
+ *    your compiler, you can try if this helps.
+ *
+ *  - Boost fails to resolve symbol names as we've already seen on some platforms. In this case, you can try again
+ *    passing the additional flag `-DICINGA2_STACKTRACE_USE_BACKTRACE_SYMBOLS=ON` to CMake and see if this helps.
+ *
+ *  In any case, please report a bug. If you run `make CTEST_OUTPUT_ON_FAILURE=1 test`, the stack trace in question
+ *  should be printed. If it looks somewhat meaningful, you can probably ignore a failure of this test case.
