Re: [Boost-users] [1.33.0][date_time] Weird warning

I got the following warning while compiling with (debian-testing) g++ 4.0.1-2

I couldn't see the problem in the code?

There may not be a problem. gcc/g++ 4.0 is more eager (too eager, in my opinion) to warn about problems in code paths for which its flow analysis can't determine reachability. If a code path is really unreachable but gcc doesn't think so, it should be possible to suppress such warnings by adding an assertion such as assert(!"This can't happen") (assuming that NDEBUG is not used).

You seem to have the wrong version of the Boost source. That function is in time_parsing.hpp, not time_duration.hpp, in version 1.33. You could install the libboost-date-time-dev package from sid instead of compiling it yourself. Ben.
