lshw is supposed to list a lot of information about hardware and it generally requires superuser access to work. However it is supposed to show limited information when run without superuser privileges. Quote from https://ezix.org/project/wiki/HardwareLiSter: "NOTE: to use some features (like DMI on x86 platforms), you need to run lshw as root or it will only report partial information." I tested it on other distribution (I think it was Mint, although I'm not sure what version of lshw was installed there) and it indeed provided some information when run by regular user. However on Gentoo it throws an exception: WARNING: you should run this program as super-user. terminate called after throwing an instance of 'std::length_error' what(): cannot create std::vector larger than max_size() Aborted lshw is used by some e.g. games which use it to determine hardware capabilities and then it is usually run without superuser access. Reproducible: Always Steps to Reproduce: 1. run lshw as normal user Actual Results: terminate called after throwing an instance of 'std::length_error' what(): cannot create std::vector larger than max_size() Aborted Expected Results: list of hardware /usr/lib/python3.7/site-packages/portage/package/ebuild/_config/KeywordsManager.py:69: UserWarning: /etc/portage/package.keywords is deprecated,

confirmed the crash
I tested this one 2 systems and it only crashed like that on one of them, strangely. But on the system where it was crashing, it is fixed with the 2.19b bump.
