I am pretty sure GDB pretty-prints C++ containers? I believe u/CuriousExploit is correct; PEDA is no longer under active development (which is fine, if you still really like that particular tool; just be aware that there won't be any new features or bugfixes unless you implement them yourself). They're both still actively maintained with a lot of helpful features. • Ghidra, Binary ninja, IDA, gdb - [ pwndbg, gef, peda ] Operating systems: • Ubuntu/Kali Linux , Windows Engineering fields of knowledge : • Computer & Software security [Focusing on Reversing, Vulnerabilities, Exploits in Linux Env.] The plugin adds custom views that try to interpret values in registers and stack as pointers and automatically dereference them.

(The issue was not observed using vanilla gdb/peda/pwndbg) This issue was first noted when using si to step through a simple ARM assembly program (noted above) when instead of exiting cleanly, gdb's disassembly failed with a SIGABRT and threw an exception: It will displays information about ELF files. One of the tools I've been hearing good things about is pwndbg, an open source plugin for GDB which aims to help with exploit development. strncat.
