Dear openmpi developers,
I have been developing our hybrid(MPI+OpenMP) application using openmpi
for five years.
This time, I tyied to install a new function, which is c++ based multi-
threaded library and it heavily repeats new and delete objects in each
Our application is so called "MPI_THREAD_FUNNELED", and openmpi-1.6
is built using --with-tm --with-openib --disable-ipv6.
My trouble is that it works very well with "--mca mpi_leave_pinned 0"
but, when mpi_leave_pinned is enabled, it often causes segfault like below.
I note that it works fine on Windows multi-threaded platform combined
with mpich2. Furthermore, regarding multi-thread(none MPI) version,
it also works fine enven on linux environment.
