Expected: ... isolatedCopy() copy_constructor(<default>-1-0) isolatedCopy() copy_constructor(<default>-2-0) isolatedCopy() copy_constructor(logger-1-0) ... Which is reasonable, considering evaluation order of function arguments is unspecified. Same thing with the other out-of-orderness later on. The test assuming evaluation order is bogus. I'll explore ways to fix. 1201245 2 beidson 2016-06-10 09:03:32 -0700 Besides out-of-orderness, the exact number of constructor calls per named object is still the same. So having a map of names-to-constructor calls will work. 1201252 3 281011 beidson 2016-06-10 09:43:09 -0700 Created attachment 281011 Patch 1201256 4 281011 achristensen 2016-06-10 09:52:06 -0700
