Hi,
I am using Valgrind-3.5.0 and LibVEX for MPI debug.
I got errors:
-------------------------------------==23712== Invalid write of size 8==23712==
at 0x40BFA9: __gnu_cxx::new_allocator<double>::construct(double*, double
const&) (new_allocator.h:104)==23712== by 0x40EEB7: std::vector<double,

If you believe this happened as a result of a stack==23712== overflow in your
program's main thread (unlikely but==23712== possible), you can try to
increase the size of the==23712== main thread stack using the
--main-stacksize= flag.==23712== The main thread stack size used in this run
was 10485760.--------------------------------------I have checked my program :
sendResultVec.push_back(generation);
It is only write an element to a vector.
vector<double> sendResultVec;
It's size is 6.
Why I got "Address 0xc0 is not stack'd, malloc'd or (recently) free'd" ?
It seems 0xc0 is a memory space owned by system.
Any help is appreciated.
thanks
