Hello,

I am using date_time library from Boost 1.36.

When running this code:

#include <boost/date_time/gregorian/gregorian.hpp>

void RunDates()
{	
        boost::gregorian::date  
today(boost::gregorian::day_clock::local_day());	
        std::string todayString=boost::gregorian::to_simple_string(today);
        boost::gregorian::date
todayFromString(boost::gregorian::from_simple_string(todayString));
}

I get a reproducible crash when calling from_simple_string command on the last line of the function.

Here is the backtrace:

The code was compiled on OSX, gcc version 4.0.1 (Apple Inc. build
5490) with Debug flags, I am linking against dynamic data_time library.

Is this a known issue in 1.36 that was fixed in 1.38? going through the list of fixes did not uncover it.

The same example compiled with release flags works without problems. I am not certain if this means that I am missing some defines or that release compile misses errors that debug catches.

Any help with this is really appreciated!

Thank you,

Alex
