From 2a992040e2ef3f9dab087be3bfac05e28596672b Mon Sep 17 00:00:00 2001 From: Erik Verbruggen Date: Wed, 9 Nov 2016 16:06:56 +0100 Subject: Fix more cases where DSE would optimize out too many stores GCC5/6 do aggressive dead store elimination on memory passed to placement-new. This resulted in the Heap::Object::prototype being a nullptr. qml.pro already contained the -fno-lifetime-dse flag, but there are other places where we ask the memory manager to allocate data. This is temporary band-aid, and is already fixed in 5.8.
