Sorry for a lengthy post, but
I got the following output from valgrind/memcheck while
I was testing mozilla thunderbird using its test framework, "make mozmill".
By running thunderbird under memgrind while it goes through
tests, I can detect where some variables are not initialized and used, or
outright memory access violations.
While I was doing it, I got the following log:
My question and request:
1. Can this unfamiliar clone be supported?
2. The dump from valgrind/memcheck afterward, i.e., the
print out of the status of threads in the program with brief
stack traces related to task synchronization looks so useful that,
I wonder, it merits a switch to print that dump when memory error is detected
during memcheck. Can you add this feature (enabled by a command line option)?
Here is a the relevant log.
I trimmed the strange very long repetition that follows PR_WaitCondVar in the
stack for each thread.
I think there is a bug in the print routine or something. We can skip printing
the same information again and again.
You can see that task 1 is the main Thunderbird thread, and other information
from this information and
without the full feature of helgrind, we may glean the overview of thread
activity from this stack dump.
Thus the request for outputting such information when memgrind detectes memory
error.
TB seems to be trying to generate a so called crash dump (triggered by other
cause( and
it tries to hard to do so when it encounteres this valgrind/memcheck limitation.
Actually, from other trace data that precedes the excerpt below,
the Lock() routine near the top of the stack,
> ==803== by 0xAD79110: mozilla::Mutex::Lock()

caused a null pointer reference inside the thread library, and that triggered
the google's breakpad
exception handler to be invoked.
So this happened not in the smooth processing of a program.

==803== Unsupported clone() flags: 0x800600
==803==
==803== The only supported clone() uses are:
==803== - via a threads library (LinuxThreads or NPTL)
==803== - via the implementation of fork or vfork
==803== - for the Quadrics Elan3 user-space driver
==803==
==803== Valgrind detected that your program requires
==803== the following unimplemented functionality:
==803== Valgrind does not support general clone().
==803== This may be because the functionality is hard to implement,
==803== or because no reasonable program would behave this way,
==803== or because nobody has yet needed it. In any case, let us know at
==803== www.valgrind.org and/or try to work around the problem, if you can.
==803==
==803== Valgrind has to exit now. Sorry. Bye!
==803==
sched status: <=== I have not asked for the following dump, but valgrind
provided it!
