I hit the same assert:

/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 = r600_sb::value*; _Alloc = std::allocator<r600_sb::value*>;
std::vector<_Tp, _Alloc>::reference = r600_sb::value*&; std::vector<_Tp,
_Alloc>::size_type = long unsigned int]: Assertion '__builtin_expect(__n <
this->size(), true)' failed.

with Google maps on Fedora 28 with mesa 18.0.5 ([AMD/ATI] Cypress XT [Radeon HD
5870]). Please see [1] for more information.
