Crashes with hardened libc

[skade]

When requiring less on Fedora 28, this happens:

irb(main):003:0> require 'less'
/usr/include/c++/8/bits/stl_vector.h:932: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::operator[](std::vector<_Tp, _Alloc>::size_type) [with _Tp = v8::Handle<v8::Value>; _Alloc = std::allocator<v8::Handle<v8::Value> >; std::vector<_Tp, _Alloc>::reference = v8::Handle<v8::Value>&; 
``std::vector<_Tp, _Alloc>::size_type = long unsigned int]: Assertion '__builtin_expect(__n < this->size(), true)' failed.
Aborted (core dumped)

This is probably due to the Fedora libc being built with _GLIBCXX_ASSERTIONS.
