--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Ah no, as I thought ... main.cpp includes a standard library header before
_GLIBCXX_DEBUG is defined, and defining it after that is too late.

You need to define _GLIBCXX_DEBUG on the command line, or before including any
other headers.
