Well, at least now we *have* a problem on the Alpha:

stage1/xgcc -Bstage1/ -B/usr/snp/alphaev6-unknown-linux-gnu/bin/ -c 
-DIN_GCC    -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long 
-DHAVE_CONFIG_H    -I. -I. -I../../gcc/gcc -I../../gcc/gcc/.
-I../../gcc/gcc/config -I../../gcc/gcc/../include ../../gcc/gcc/reload.c
-o reload.o
../../gcc/gcc/reload.c: In function `find_reloads':
../../gcc/gcc/reload.c:4217: In basic block 407:
../../gcc/gcc/reload.c:4217: Flow control insn inside a basic block
(jump_insn 14561 4779 14562 (set (pc)
        (label_ref 4787)) -1 (nil)
    (nil))
../../gcc/gcc/reload.c:4217: confused by earlier errors, bailing out

"Flow control insn inside a basic block" - looks pretty damning to me.
