/**
 * Automatically launches GDB Debugger TUI during crash.
 *
 * Run the following inside a terminal:
 *
 *     sudo apt install gdb
 *     make -j12 o//examples/auto-launch-gdb-on-crash.com
 *     o//examples/auto-launch-gdb-on-crash.com
 *
 * Backtrace is logged instead if run outside interactive terminal. We
 * also don't auto-launch GDB on non-Linux since the development tools
 * on other platforms generally can't be relied upon to correctly debug
 * binaries built with a Linux toolchain. Environmental factors such as
 * GDB, MAKEFLAGS, ADDR2LINE, TERM, and isatty(STDERR_FILENO) should
 * also be taken into consideration:
 *
 *     $ export GDB=eoatuhshtuone
 *     $ o//examples/auto-launch-gdb-on-crash.com
 *     error: Uncaught SIGTRAP
 *     etc. etc.
