Valgrind

[stevenrbrandt]

It would be nice if HPX applications could be checked/debugged with valgrind. Can this be made to work?

It should be possible, however I'd definitely need help with this.

Just checked with examples.quickstart.hello_world valgrind seems to run but reporting many errors. Hopefully those are false positives.

That's exactly what this ticket was about. Steve asked whether we could get rid of those error messages as they make it impossible to find genuine problems.

I had a look and most of the errors are related to boost and they mention on their website that this is a known issue and you need compile boost with valgrind=on option.

Running programs that switch stacks under valgrind causes problems. Property (b2 command-line) valgrind=on let valgrind treat the memory regions as stack space which suppresses the errors. Users must define BOOST_USE_VALGRIND before including any Boost.Context headers when linking against Boost binaries compiled with valgrind=on.

I think this can be closed as it has been shown to work. Feel free to reopen if needed.
