It looks to me like this test has undefined behaviour? That is, it is calling last_value with a non-void return value with no slots connected (assuming tracking is working).
Good point. I tried to modify the test so that it throws in short_lived_2::f() instead, but that seems to work fine. I tried a standalone test program with 1.33.1, HEAD, and RC_1_34_0_freeze, and only 1.33.1 seems to show the problem I was trying to demonstrate. Sorry for the noise. Zach Laine
