Cursed knowledge unlocked:

--recursion-limit
--no-recursion-limit
Enables or disables a limit on the amount of recursion performed whilst demangling strings. Since the name mangling formats allow for an infinite level of recursion it is possible to create strings whose decoding will exhaust the amount of stack space available on the host machine, triggering a memory fault. The limit tries to prevent this from happening by restricting recursion to 2048 levels of nesting.

I'm not sure I want to even know how or in what circumstances demangling of symbol names can cause a literally infinite recursion ...

I wonder which demangler has this property. Looking at cplus_demangle_name_to_style from libiberty I see gnu-v3 (C++), java, gnat (Ada), dlang (D), and rust in there.

Sourceware thanks @conservancy for their support and urges the community to support Conservancy

#Sourceware has only been a Software Freedom Conservancy member project for just 6 months. But the story started a long time ago and a lot has happened in that time:

We hope the community will support the Software Freedom Conservancy 2023 Fundraiser and become a Conservancy Sustainer https://sfconservancy.org/sustainer

#Sourceware @ #Fosdem

Various Sourceware projects will be present at @fosdem plus various overseers and of course @conservancy staff.

Get your talk submissions in before end of the week (December 1st) to these developer rooms:
