Package: coinor-libipopt1
Version: 3.11.4-1
Severity: important
Ipopt/src/Algorithm/LinearSolvers/IpMumpsSolverInterface.cpp calls MPI_Init.
This causes programs using MPI themselves to abort as MPI_Init gets called
twice:
--------------------------------------------------------------------------
Calling MPI_Init or MPI_Init_thread twice is erroneous.
--------------------------------------------------------------------------
[snout:10806] *** An error occurred in MPI_Init
[snout:10806] *** on communicator MPI_COMM_WORLD
[snout:10806] *** MPI_ERR_OTHER: known error not in list
[snout:10806] *** MPI_ERRORS_ARE_FATAL: your MPI job will now abort
I've attached a patch that removes the call to MPI_Init.
