Hi,

Is there some sort of size limitation on the object code produced with
-fbounds option.   When I compile with all the options listed except for
-fbounds, it compiles and executes without any problem.   But once I add in
the -fbounds option I get "reloc overflow" error.  Can someone help.   

Here is what happens when I compile with -fbounds option: 

g77 -v -fbounds-check -g -fdebug-kludge -Wall -O -fno-automatic
-fno-backslash -ff90 -malign-double -march=i586  -c xxx.f -o xxx.o
