In working with my date/time code I've encountered another problem with Boost. I can reproducibly get lexical_cast to segfault. It happens when a greg_month is lexical_cast to a string. I don't observe this behavior for years or days, just months. The segfault can be avoided by using lexical_cast<string, int> instead of lexical_cast<string>, but this shouldn't be necessary.
Test case (note that WinXP doesn't complain when programs segfault, hence the Begin/End business):
crash.cc: ---- #include <boost/lexical_cast.hpp> #include <boost/date_time/posix_time/posix_time.hpp> #include <iostream> using namespace std; using namespace boost; using namespace boost::posix_time; using namespace boost::gregorian;
int main() { const ptime t(date(1969, Jul, 21), time_duration(2, 56, 15));
cout << "Begin!" << endl; cout << lexical_cast<string>(t.date().month()) << endl; cout << "End!" << endl; }
WinXP, vs.NET2003 (both debug and release builds) boost from anonymous cvs updated:
2003-08-05
10:00
that's MST.
Begin! 07 End! Press any key to continue
I'm sorry I haven't built the libraries for my cygwin recently, I'll have to update my "get latest boost" script
