Possible bug in C++ compiler of Intel compiler suite 2018

when I tried to install the PETSc 3.8.0 complex version I got

gmake[2]: *** [arch-linux2-c-opt/obj/src/mat/impls/baij/seq/baijsolvtrannat.o] Error 4
gmake[2]: *** Waiting for unfinished jobs....

This error occurs only with -O2, the default optimization.

My workaround was to turn off optimization for the 3 routines that crashed and the rest went fine.
