Description
Hi.
There is an issue with the way the buffer is allocated in lib_mpp.F90 for buffered sends.
The buffer variable is defined as a local variable (tampon) in mpi_init_opa and allocated within this routine. However I believe that for Fortran-95 local allocatable arrays are supposed to be automatically deallocated when you exit the routine. With our workstations compiler (PGI version 7.1.4 + LAM mpi) I get a SIGSEGV when using due to the tampon array not longer being available.
By moving the tampon array into the heading of the module it works. I believe, that this is a general problem with all F95 compilers and this fix (or another fix) should go into the next version.
At the same time maybe the declaration of tampon should be changed from REAL(kind=8) to REAL(kind=wp).
