GNU GDB 10.2 debugging a crashed program.

gdb is a debugger that can handle programs written in C, C++, Go, Rust and a rather long list on other languages. It works on GNU/Linux, Windows and many other operating systems running on a variety of architectures ranging form x86-64 to ARM to RISC-V.

GDB 10.2 is the second bug-fix release for the GDB 10.x branch released on September 13th, 2020. There are no new features in it, just bug-fixes.

The release announcement lists the following bug-fixes since 10.1 was released on October 24th, 2020:

The source code for GDB 10.2 can be acquired from and the home page is at

GDB was initially released all the way back in 1986. It is the standard go-to debugger on GNU/Linux, so you do not have to install it from source unless you really want to, all the GNU/Linux distributions have it available in their repositories. Compiling it is strait forward with ./configure && make if you want to go that route. Compiling with make -j$(nproc) takes about 10 minutes on a modern multi-core x86-64 CPU. Do be aware that there is no make uninstall if you install it from source, all the Makefile has to offer for uninstall functionality is @echo "the uninstall target is not supported in this tree"...
