[petsc-users] Caught signal number 10 BUS: Bus Error

[Justin Chang]

Hello everyone,

My program runs fine, with debug mode, on my Ubuntu laptop, but when I run
the same code on my iMac (Yosemite) with no debug, I get this error:

[0]PETSC ERROR:
------------------------------------------------------------------------
[0]PETSC ERROR: Caught signal number 10 BUS: Bus Error, possibly illegal
memory access

--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 59.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------
-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status,
thus causing
the job to be terminated. The first process to do so was:

  Process name: [[11164,1],0]
  Exit code:    59
--------------------------------------------------------------------------

Can someone explain what this error means to me? Basically, I have an FEM
code (using DMPlex), with auxiliary field coefficients, and this error
occurs when I compute the Jacobian via SNESComputeJacobian(...). This error
doesn't happen on my Ubuntu laptop.

Thanks,
