Commit bug reported by Alexander Kobotov (INTEL) on LAPACK Forum
Link: http://icl.cs.utk.edu/lapack-forum/viewtopic.php?f=13&t=4762&p=11439#p11439
Recent commit r1533 introduced out of bound access which could lead to a crash.
It results scaling of a vector instead of a single number.
Fix is simple:

zhgeqz.f:669
- CALL ZSCAL( ILAST, SIGNBC, H( ILAST, ILAST ), 1 )
+ CALL ZSCAL( 1, SIGNBC, H( ILAST, ILAST ), 1 )

Similar for chgeqz on line 668
