Sounds like you need more memory.

 --00:00:00:00.000 27357----read-var-info=yes

This is possibly the cause of the problem.  Remove it.

Removing --track-origins=yes might also help a bit.

I backed out r12466 just a few minutes ago, as r12813.  So the
unmodified ToT should work ok for you now.

Pls let me know any other critical failures on OSX asap.  I am 
planning to finalise OSX patches for the upcoming 3.8.0 release
in the next 24 hours or so.

Hi Julian,

I just synced to r12813 and I'm still getting an error when running an
arbitrary WebKey layout test under Valgrind (see output below).

Nikolas - can you give this a try and see if you get the same results?

[Valgrind-users] Using System Call in a Valgrind Tool

2012-08-02 Thread Wonjoon Song 
Hello All

I am trying to build a new tool using valgrind. I'm also trying to use mmap 
system call to get huge memory block in my tool. When I use do_syscall in my 
tool I get an error message like this. I tried several other calls (getpid, 
etc) and every time I get this segmentation fault error.


===

--24479-- VALGRIND INTERNAL ERROR: Valgrind received a signal 11 (SIGSEGV) - 
exiting
--24479-- si_code=1;  Faulting address: 0x52;  sp: 0x629a2dc0

valgrind: the 'impossible' happened:
   Killed by fatal signal
==24479==at 0x38059A25: vgPlain_do_syscall (m_syscall.c:72)
==24479==by 0x3808E5E1: handle_syscall (scheduler.c:1057)


===

I tried to search for examples using system call in tools but it seems 
they(memcheck, massif, lackey) don't use it.

My question is, is it allowed to use system call in a valgrind tool? Is it 
recommended not to use system call? If it is allowed to use system call in a  
tool, what should I do to make this thing work?

I use valgrind-3.8.0.SVN, and 32 bit Ubuntu 12.04, which is a VM.

Thank you,
Wonjoon Song

[Valgrind-users] Valgrind on Mountain Lion

2012-08-02 Thread Jacob Goldstein 
Has the ToT valgrind been tested on OS X 10.8 Mountain Lion?  Appears to 
perform different than on Lion, but I'm guessing Mountain Lion isn't support 
yet?
