>Description:
On an alpha running Tru64 4.0f, when compiling c-parse.c from application 126.gcc of SPECInt95 with the flag -ffixed-\$15, I get interenal compiler error. Other flags, such as -ffixed-\$14 don't induce the error. Similarly, other c files compile OK with the -ffixed-\$5 flag. Here is the command line that produces the error:
main% /projects/smt11/redstone/usr/local/bin/gcc -v -save-temps -c -o c-parse.o -DSPEC -O3 -mcpu=ev6 -ffixed-\$15 c-parse.c
