Oh, in that case, then this is expected, though undesired.  In older 
versions of MySQL++, str() has a mode where it will auto-reset Query's 
string buffer after returning the string, and execute() uses this in 
versions prior to v2.2.0 unless it's a template query.  So, when you 
come along and call str() a second time, the buffer's already been emptied.

Since you're going to have to upgrade to fix this, I recommend waiting 
for v3, which may come out as early as next week sometime.

If upgrading isn't an option, then you'll just have to call str() ahead 
of execute() to save the buffer in a temporary location that your 
exception handler can find.

But I highly recommend upgrading.  MySQL++ has come a long, long way in 
the past two years.
