Dear, I would like to know if there are unimplemented checks related to throw qualifiers. E.g., if I have two methods int theClass::oneMethod() throw (AnException) { throw AnException(); return 1; } int theClass::otherMethod () throw () { return oneMethod(); } Should this be an error? gcc does not complain about that. In addition, if I use the method this way try { otherMethod() } catch(AnException); the exception is not catched (because of the "throw ()", I guess). This seems to be quite strange, I think that the idea of using throw qualifiers is to enforce that the only exceptions the caller needs to catch are those declared in the qualifier. So, the "throw ()" should not be possible. I think that the throw () should be possible only if all the invocations to methods throwing exceptions are enclosed into try { } catch blocks. Quoting the manual, is it a "Regrettable thing we can't change" or a "Known problem"? Cheers, Sergio
