[rrd-users] rrdtool[2489]: segfault while creating grafic

[thd01]

Hi Tobi,

sorry or the delay.
I've done some tests. I've upgradet my system to 10.4, but 
I get the same error. I've tried on an other maschine, there I get no
errors?!
That's what I don't understand!

just for information:

valgrind: m_mallocfree.c:225 (mk_plain_bszB): Assertion 'bszB != 0' failed.
valgrind: This is probably caused by your program erroneously writing past
the
end of a heap block and corrupting heap metadata.  If you fix any
invalid writes reported by Memcheck, this assertion failure will
probably go away.  Please try that before reporting this as a bug.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.
