log

Helgrind crashes for me.
I am using the latest 3.5.0, but this also happens in 3.4.0.
3.3.0 however doesn't crash.
Attached is the log from helgrind. I can forward a core dump if needed, it is just too big to upload.
Please let me know if there is any other information that might be helpful.

Comment 1 Julian Seward 2009-11-13 21:25:26 UTC

Why do you say Helgrind crashed?  I don't see any evidence for that
in the attached log.  Usually when it crashes there is some
associated error message and/or backtrace.  I'd need to see that.

It produced <helgrind log file>.core.<pid> core dump.
The run did not finish and helgrind did not produce the summary at the end.
This run does not crash when running without helgrind, and with valgrind version 3.3.0 it also manage to finish.

So far you haven't actually provided any information at all (log files
showing the crash happening, or a way to reproduce it) that I can look
at to see/diagnose the problem.

Comment 4 Tal 2009-11-18 05:26:49 UTC

Maybe this will be more helpful.
I also have a core dump, well two core dumps, I assume one from helgrind and one from my application.

Please .. can you post the _complete_ output rather than the part you
_think_ is relevant -- comment #4 looks like a smaller part of a
bigger log.

Comment 7 Julian Seward 2009-11-23 23:44:12 UTC

I can guess what's going on here, but I'd need more info.

Does Memcheck report any invalid memory accesses on this
program?  Can you post its output?

Comment 9 Julian Seward 2009-11-24 00:22:43 UTC

Well, my guess is that Valgrind is crashing in the C++ name
demangler, as a result of these incredibly long symbol names.
So it's a problem in the Valgrind core, nothing specifically
to do with Helgrind.

That's only a guess though.  Without a repro case this is going
to be hard to fix.  One approach is to write a condensed C++ test
case that generates symbols with the very long names listed
in comment #4, and see if that can be made to crash Helgrind.

Comment 10 Tal 2009-11-24 00:30:32 UTC

Thanks.

Sounds like a good guess. I'll give it a go and let you know.

Comment 11 Tal 2010-01-12 01:30:33 UTC

Julian,

I've tried unsuccessfully so far to reproduce this crash on a small example. I did however did a run on a different machine which gave me a bit more info and a backtrace that might be more helpful. Please see attached.

Also, my program is loading objects and functions at run time. Could that be of an issue with 3.5.0?

Comment 13 Julian Seward 2010-02-15 11:54:40 UTC

I suggest 2 things:

1. make sure the program runs without any errors with
   --tool=memcheck.  If you see errors, especially invalid writes,
   fix them.

2. try with --demangle=no

Comment 14 Julian Seward 2010-02-21 14:24:01 UTC

Setting to NEEDSINFO/WAITINGFORINFO.  I'd like to fix this, but
you'll need to supply a small self contained program that I can
use to reproduce the problem here.
