Hi,

I won't be able to fix the problem if it is in the boost library, I am afraid, but I could try to help narrowing it down. If there is a bug in the boost code, you should file a bug report. I don't know how to. Even so a previous attempt was unsuccesful. I got a strange http error (the last time).

Could you send a short sample code which should compile but does not (~10 lines)?

Code compiles but gives a runtime error (through the checked iterators): // use time_put facet to create final string return std::use_facet(a_ios.getloc()).put(next, a_ios, fill_char, &tm_value, &*a_format.begin(), &*a_format.begin()+a_format.size());

Which boost version are you using? 1.37

ok, sorry, should have been more specific there: Could you send a short but "complete" sample which compiles but crashes? It should contain a main function which does serves only one purpose: Demonstrate the problem in as little code as possible (but as much as necessary to actually be able to create a program from it).

Something like this would be useful to attach to a bug report, too.

I already understood that the first time. However it takes me some time to peal of the unnessary parts to create a test case, since it happens during streaming of a date time when a facet is set. However from the Date.Time code one can clearly see that it is incorrect. This is only allowed if the specifications explicitly state that the format string may not be empty.

Filing a bug report should work (never had a problem), starting from here:

http://www.boost.org/support/bugs.html

I got an error about an invalid certificate, but maybe I will give it a try.

I have created a case: #include #include #include <sstream> int main() { boost::gregorian::date date(2009, 1, 1); boost::posix_time::time_duration td(0, 0, 0, 0); boost::posix_time::ptime boost_time(date, td); std::stringstream sstr; boost::posix_time::time_facet* pFacet = new boost::posix_time::time_facet (""); sstr.imbue(std::locale(std::locale::classic(), pFacet)); sstr << boost_time; return 0; } I will post it if possible. (thx btw)

Glad to read that! Regards, Roland
