Hi,
I'm trying to initialize a dynamic_bitset<unsigned char> from a vector
of blocks. Here's the code:
#include <cstdlib>
#include <vector>
#include
typedef boost::dynamic_bitset<unsigned char> BitSet;
typedef std::vectorBitSet::block_type Block;
int main(int argc, char* argv[]) {
int nbits = atoi( argv[1] );
BitSet bits( nbits );
Block buffer;
buffer.resize( bits.num_blocks(), 0xff );
boost::from_block_range(buffer.begin(),buffer.end(), bits );
return 0;
}
If the bitset size isn't a multiple of sizeof(unsigned char) (here 8)
, ~dynamic_bitset() throws an exception.
For example:
% ./a.out 1
a.out: boost-1.60.0/include/boost/dynamic_bitset/dynamic_bitset.hpp:633:
boost::dynamic_bitset::~dynamic_bitset()
[with Block = unsigned char; Allocator = std::allocator<unsigned
char>]: Assertion `m_check_invariants()' failed.
Aborted
% ./a.out 8
% ./a.out 15
a.out: boost-1.60.0/boost/dynamic_bitset/dynamic_bitset.hpp:633:
boost::dynamic_bitset::~dynamic_bitset()
[with Block = unsigned char; Allocator = std::allocator<unsigned
char>]: Assertion `m_check_invariants()' failed.
Aborted
% ./a.out 16
%
I see this with 1.59 & 1.60 using either g++ 4.7.2 or Apple LLVM
version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)
I believe that I'm following the rules for the buffer type and size.
Is there something I'm missing?
Thanks!
Diab
