Fortran testcase
Turns out the same error message occurs with SPEC CPU2000's 178.galgel, more
specifically when compiling the lapak.f90 file using one of the following flag
combinations:
-O1 -fno-ira-share-save-slots -fcaller-saves -ffixed-form
-O2 -fno-ira-share-save-slots -ffixed-form
-O3 -fno-ira-share-save-slots -ffixed-form
-Os -fno-ira-share-save-slots -ffixed-form
A testcase reduced mainly with delta is attached. To reproduce the error, just
use:
gfortran -O2 -fno-ira-share-save-slots -ffixed-form testcase.f90
