--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The testcase linked OK with 4.4 but not 4.5, so I suspect it started to fail
after r154054 which moved the recursive_init_error definition into the cxxabi.h
header.

The symbol was already missing from libstdc++.so in 4.4, but didn't cause a
linker error because it wasn't declared in the header.
