--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The crash started with r260383:
Aliasing 'this' in a C++ constructor
2018-05-18 Marc Glisse <marc.gli...@inria.fr>
PR c++/82899
gcc/
* tree-ssa-structalias.c (create_variable_info_for_1): Extra
argument.
(intra_create_variable_infos): Handle C++ constructors.
gcc/testsuite/
* g++.dg/pr82899.C: New testcase.
And was fixed on trunk by r270906
PR tree-optimization/90328
* tree-data-ref.h (dr_may_alias_p): Pass in the actual loop nest.
* tree-data-ref.c (dr_may_alias_p): Check whether the clique
is valid in the loop nest before using it.
(initialize_data_dependence_relation): Adjust.
* graphite-scop-detection.c (build_alias_set): Pass the SCOP
enclosing
loop as loop-nest to dr_may_alias_p.
* gcc.dg/torture/pr90328.c: New testcase.
It's also fixed on gcc-9-branch, presumably by the backport of that patch, as
r271995 (although I didn't verify that explicitly).
So this is a dup of PR 90328.
