C++ test case (test.ii); compile with "g++ -flto -fsanitize=address" - and try
to run

Running

   g++ -flto -fsanitize=address test13.ii && ./a.out

causes the attached program to fail with:

--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Hmm, the problem turns out to be more subtle: I compiled the same program on
CentOS 6.4 and on openSUSE 13.1. Result:

* On CentOS, both binaries fail with the assert (also independent of the use
  of a linker plugin)
* On openSUSE, both binaries work fine.

Also copying libasan.so to the other system made no difference. While without
-flto, the code runs fine on CentOS 6.4.

Works for me in GCC 4.9.0 even (on https://godbolt.org/).
Since there is no way to reproduce this closing as works for me.
