Hi,

I'm experiencing some ungraceful crashes here using either of

   Tpetra::Vector::replaceGlobalValue()
   Tpetra::Vector::sumIntoGlobalValue()

with something like

============================== *snip* ==============================
*** glibc detected *** 
../build/mpi/executables/piro-driver/piro-driver.exe: double free or 
corruption (out): 0x00000000028271c0 ***
======= Backtrace: =========
/lib/libc.so.6(+0x72966)[0x7f2cefbcb966]
/lib/libc.so.6(cfree+0x6c)[0x7f2cefbd071c]
[...]
============================== *snap* ==============================

Their local equivalents work all right.

This is with Trilinos 10.4 on a simple two core build, openmpi 1.4.1, 
GCC 4.4.3.

Anyone with similar experiences?

Cheers,
Nico
