Public bug reported:
Binary package hint: gcc-4.3
Running the tests for boost dynamic bitset from svn, g++-4.2 passes all
tests, but g++-4.3 rejects them with an error:
In file included from bitset_test.hpp:26,
from dyn_bitset_unit_tests1.cpp:11:
../../boost/dynamic_bitset/dynamic_bitset.hpp: In member function ‘size_t
boost::dynamic_bitset<Block, Allocator>::count() const’:
../../boost/dynamic_bitset/dynamic_bitset.hpp:1015: error: ‘mode’ cannot appear
in a constant-expression
../../boost/dynamic_bitset/dynamic_bitset.hpp:1015: error: template argument 1
is invalid
../../boost/dynamic_bitset/dynamic_bitset.hpp:1015: error: expected `>' before
‘*’ token
../../boost/dynamic_bitset/dynamic_bitset.hpp:1015: error: expected `(' before
‘*’ token
../../boost/dynamic_bitset/dynamic_bitset.hpp:1015: error: expected
primary-expression before ‘>’ token
I have reduced the problem to a minimal test case, gcc43regression.cpp,
which is attached. If you process this with "g++-4.2 -S
gcc43regression.cpp", it will succeed, but "g++-4.3 -S
gcc43regression.cpp" will fail.
