Bug ID: 71529
Summary: [7 regression][CHKP] ICE in expand_expr_real_1
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: ienkovich at gcc dot gnu.org
Target Milestone: ---
This fail starts with r236299. Looks like it happens because 'this' parameter
of instrumented constructor has wrong DECL_CONTEXT (not instrumented version of
function is used).
