Subject: [Valgrind-users] copying uninitialized values =09 =09 Hi, Would it be possible to report copying of an uninitialized value when 4 contiguous bytes (or more) are copied at once? Why not report such cases? It's a nightmare trying to track where uninitialized values are coming from...

I already started doing something similar to what that macro does, but this means spending time deciding where to add the check + recompiling + rerunning Valgrind (which takes several days sometimes). And I'll never get around to doing this for all the uninitialized value messages (our application is huge). Also, Valgrind's treatment of uninitialized values is very confusing to new users. They usually just conclude that Valgrind isn't helpful and move on to other debugging methods (remember that users are stupid creatures :-)) Meir -----Original Message----- From: Julian Seward [mailto:js...@ac...]=20 Sent: Monday, August 21, 2006 6:38 PM To: val...@li...
