When running octave, either in gui mode or in shell mode, this code makes the
program quit with the error reported below:


n = 150;
A = rand(n) + rand(n)*1j;
b = rand(n,1) + rand(n,1)*1j;
x = A\b;



the error reported is:
ZLASWP: parameter number 6ZLASWP: parameter number 6 is invalid is invalid

terminate called after throwing an instance of 'octave::execution_exception'
  what():  Fortran procedure terminated by call to XERBLA
fatal: caught signal Aborted -- stopping myself...
Aborted (core dumped)

My system is debian testing, using the official octave 8.3.0 debian package
installed with apt (This behavior happened also on the same machine running
the debian stable distribution, octave 7.3.0). My processor is an Intel(R)
Core(TM) i7-6500U CPU @ 2.50GHz.
