Bug ID: 68164
Summary: Destructor side effect unexpectedly elided
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: webrown.cpp at gmail dot com
Target Milestone: ---

Test program
Compiler version: g++-mp-6 (MacPorts gcc6 6-20151025_0) 6.0.0 20151025
(experimental).
Compiling via: g++-mp-6 -Og -std=c++1z
The enclosed test program improperly asserts because (it seems) that the
assignment in the body of B's destructor is elided.
The program does not assert, however, if I insert a debugging output statement
(marked #1) following the assignment.
Comment #1 out to see the unexpected failed assertion. Repositioning #1 to
precede the assignment also results in a failed assertion.
