Hello Daniel,
I am using the following code on my macbook.
mpirun -n 1 xterm -e lldb ./test : -n 1 ./test
This is the debug information I get from lldb. Is it useful?
(lldb) run
Process 99662 launched: './test' (x86_64)
Process 99662 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS
