reduced testcase
I think the code has defined behaviour. The temporal object created by A() is
afaict alive when the pointer comparison is being done (but it is not when the
result of the comparison is being used)... but it might easily happen that I am
wrong; I am certainly not an C++ expert, the code is quite artificial.
Attached is a reduced testcase.
Output:
$ g++ -O2 testcase.C
$ ./a.out
a.out: testcase.C:16: int main(): Assertion `!r' failed.
Aborted
