Hi,
I am running a C++ program with OMPI.I got error:
*** glibc detected *** /nsga2b: free(): invalid next size (fast):
0x01817a90 ***
I used GDB:
=== Backtrace: =Program received signal SIGABRT,
Aborted.0x0038b8830265 in raise () from /lib64/libc.so.6(gdb) bt#0
0x00
thanks,
I forgot to set up storage capacity for some a vector before using [] operator
on it.
thanks

Getting deeper into valgrind- and debugger-identified errors is somewhat
outside the scope of this mailing list -- we're really here to talk about Open
MPI-related things.
I suggest you read the valgrind documentation and/or google around for other
memory debugging resources.
Good luck.

It's not hard to test whether or not SELinux is the problem. You can
turn SELinux off on the command-line with this command:
setenforce 0
Of course, you need to be root in order to do this.
After turning SELinux off, you can try reproducing the error. If it
still occurs, it's SELinux, if it does

Hi,
Thanks for your reply. I tried to execute first a process by using
mpirun -machinefile hostfile.txt --slot-list 0:1 -np 1
but it gives the same as error as mentioned previously.
Then, I created a rankfile with contents"
