Further poking revealed that the patch above mishandles
// PR c++/86769
// { dg-do run }
#define assert(X) do { if (!(X)) __builtin_abort(); } while(0)
int g;
struct X {
X() { g++; }
~X() { g--; }

For easy reproduction: https://godbolt.org/g/dfZFxz
This does not appear to be a regression: this example appears to be miscompiled
by every version of GCC back to at least 4.1.
