middle-end/101480 - overloaded global new/delete
The following fixes the issue of ignoring side-effects on memory
from overloaded global new/delete operators by not marking them
as effectively 'const' apart from other explicitely specified
side-effects.
This will cause
FAIL: g++.dg/warn/Warray-bounds-16.C -std=gnu++1? (test for excess errors)
because we now no longer statically see the initialization loop
never executes because the call to operator new can now clobber 'a.m'.
This seems to be an issue with the warning code and/or ranger so
I'm leaving this FAIL to be addressed as followup.
