[Bug c++/32182] -fstrict-aliasing optimizations cause constructor not to run for object causing segfault

["epperly2 at llnl dot gov" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #2 from epperly2 at llnl dot gov  2007-06-01 20:53 -------
To avoid depending on system #include files, the example has
typedef unsigned int size_t;
hardwired in the code.  This may be an incorrect definition for some platforms.

Oddly enough, if I delete NextClass and make TestClass inherit directly from
BaseClass, the program no longer segfaults.

I am not sure if all the features of this example are strictly necessary. I
basically created a new program from scratch that has the same characteristics
as the original 100+K program, and I added things until it reproduced the same
behavior.
