I've never used it and only know of one guy that has:   http://stackoverflow.com/questions/2924058/confused-about-stdruntime-error-vs-stdlogic-error/6476858   He (Vladimir) said he was thinking about stopping using it a few years ago.   Brian Ebenezer Enterprises - In G-d we trust. http://webEbenezer.net

C++ exceptions are broken.

I also don't understand how it *could* happen, since the compiler generates exception-handling instructions, and the language per se doesn't define logic_error.   Why do you say logic_error is "more serious" than runtime_error? Semantically that's not true, insofar as seriousness is not defined by the library. I guess you mean that -- assuming they're used as intended -- a logic error could have been avoided by the programmer, whereas a runtime error could not. Depending on the situation, though, either one can leave the user high and dry.   --jkl     -- [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.
