Details:

I have written a piece of native code to implement an alternative to
'pararrayfun' from parallel package. I need this alternative because from
octave 4.4.1, parallel package doesn't work.

I have added some unit test for my pararrayfun implementation, and was testing
it when octave crashed (terminated with signal SIGABRT). 

How to build the oct-file:
$ export CXXFLAGS="-ggdb -Wall -O0"
$ mkoctfile -g -DDEBUG -o pararrayfun.oct pararrayfun.cc

This is the stack trace I get from the corresponding core dump using gdb:
