Description
Hi, I am using mpiP 3.5.0 to do profiling for [WRFV-3.9.1.1](https://github.com/NCAR/WRFV3/releases/tag/V3.9.1.1). I built mpiP with [Open MPI 4.0.5](https://www.open-mpi.org/software/ompi/v4.0/)
```
./configure --prefix=$MPIP_ROOT --disable-libunwind CC=/path/to/mpicc CXX=/path/to/mpicxx F77=/path/to/mpif77
```
and pre-load it in my mpirun as
```
mpirun -x "LD_PRELOAD=/path/to/libmpiP.so" ....(other mpi arguments) wrf.exe
```
I can see mpiP printed in the stdout as
```
mpiP:
mpiP: mpiP V3.5.0 (Build Dec 18 2020/00:20:30)
mpiP:
```
But there is no final report generated and no error message was printed. Could you help provide any suggestions on debugging this issue? The application is coded with fortran 90. But I used mpiP to do profiling for the simple mpif90 program [ring_usempi](https://github.com/open-mpi/ompi/blob/master/examples/ring_usempi.f90) and do not have such issue.

Research direction
Compare the WRFV-3.9.1.1 launch with the working ring_usempi.f90 run, starting from the mpiP 3.5.0 output and the LD_PRELOAD setup in mpirun. Check the Open MPI 4.0.5 configuration and determine why no final report is produced; done when the cause is reproducible or a report is generated.
