- From: "Rebecca N. Palmer" <rebecca_palmer@zoho.com>

Package: g++-9
Version: 9.2.1-23
Control: affects -1 src:beignet
Trying to build beignet with llvm 10 and the default -std fails with
this internal compiler error. (See attached for exact changes; it
previously used -std=c++0x, but that fails with LLVM 10 because it can't
find std::index_sequence.)
_Possibly_ this upstream bug:
https://gcc.gnu.org/ml/gcc-bugs/2019-11/msg02364.html
(The error says to attach the full preprocessed source, but it's ~2M
which I suspect is too big to be allowed here.)
