Subject: [PATCH 14/17] Conditionalize tests for PR libstdc++/98466 on
__LIBSTDCXX_SO_VERSION >= 11
The tests:
23_containers/deque/debug/98466.cc
23_containers/unordered_map/debug/98466.cc
were added upstream 2021-01-01 as part of:
libstdc++: Implement N3644 for _GLIBCXX_DEBUG iterators
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=05a30af3f237984b4dcf1dbbc17fdac583c46506
but fail when run in DTS against a system libstdc++.so
from an older GCC.
In particular, they use the older implementation of _M_can_compare from
the dynamic library:
$ eu-readelf -s 98466.exe | grep can_compare | c++filt
11: 0000000000000000 0 FUNC GLOBAL DEFAULT UNDEF __gnu_debug::_Safe_iterator_base::_M_can_compare(__gnu_debug::_Safe_iterator_base const&) const@GLIBCXX_3.4 (4)
157: 0000000000000000 0 FUNC GLOBAL DEFAULT UNDEF __gnu_debug::_Safe_iterator_base::_M_can_compare(__gnu_debug::_Safe_iterator_base const&) const@@GLIBCXX_3.4
