------- Comment #21 from johnw at gnu dot org 2009-10-25 05:40 -------
I'm actually getting this same error on Snow Leopard (Mac OS X 10.6.0). It's
pretty easy to reproduce with Boost (1.40):
#include <string>
#include <sstream>
#include <boost/variant.hpp>
int main()
{
std::ostringstream buf;
boost::variant<bool, std::string> data;
data = buf.str();
data = false;
return 0;
}
$ g++ -I/opt/local/include -o bug bug.cc
What happens here is that ostringstream, which is in libstdc++.dylib, returns
an empty string which does not match the notion of empty string compiled into
my executable; thus when Boost tries to deconstruct the string it stored in
order to store the boolean, it crashes trying to deallocate a foreign lib's
empty string.
This doesn't happen with the same Boost using the stock compiler (g++ 4.2).
