Good evening, I am trying to use the callgrind profiler to profile my C++
program. I am using Valgrind version 3.6,1 on Linux Centos Version 5.5 on a
Intel 32-bit processor. I keep getting the following error(shown
below) when I try to profile my program.
I already used Linux gprof but it didn't provide any
useful profiling information. Please tell me what I am doing wrong or what
workaround I should use. Thank you

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.
