Detailed description of problem
Trying to use the Ember OTF2 motif to replay a trace containing an MPI_Bcast will cause the simulation to hang. The motif loads the trace successfully, but then the simulation never completes.
Describe how to reproduce the issue
Generate the trace of an MPI application containing a Bcast. Then compile sst-elements with OTF2 support and use the Ember OTF2 motif to read that trace with addMotif("OTF2 tracePrefix=traces.otf2").
What operating system and versions
TOSS 4.8-2.
What versions of external libraries (MPI, etc.)
otf2 3.0.3
openmpi 4.1.2
