[Valgrind-users] Feature request - backtrace on warning set address range perms
Feature-request: Add backtrace to output for these warnings: Warning: set address range perms: large range [0x4c339040, 0x206094130) (undefined) Explanation: This was a large allocation which ate up all my memory when debugging with valgrind making it hard for me to find where it happened. The reason was an undefined integer in a class (uninitialized memory). Valgrind only gives this one line warning (which is good), but it would also be nice if it would give a backtrace for this... Might have helped me to track down this bug sooner :) -- With kind regards Jonatan Wallmander Vovoid Media Technologies AB -- Own the Future-Intelreg; Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.

The best would be to file a bug in bugzilla, for the false negative
caused by code such as:
{
size_t undef;
char *p = malloc (undef);
}
Too late to file a bug in bugzilla :).
An improvement has been committed in revision 13361.
False negative in malloc lib replaced functions should be solved now.
E.g. a call to malloc with undefined size will now cause an error
to be detected by memcheck.

Re: [Valgrind-users] using valgrind at specific point while running program

However my problem is different. There are iterative functions. So I want to start valgrind after, say, 0.5 hours of execution to see what is going on. Sorry, don't think that's possible - valgrind has to run from the start... Since it's a VM after all. One thing I've done is to use multi-threading whenever possible - valgrind runs in multipe threads as well.. That can speed up the time for your program. /jaw -- Introducing Performance Central, a new site from SourceForge and AppDynamics.
