------- Comment #31 from pluto at agmk dot net  2005-11-22 00:59 -------
w/o patch still ICEs:

# ppc:

stage1/xgcc -Bstage1/ -B/usr/ppc-pld-linux/bin/ -c -O2 -ggdb -gnatpg -gnata
-g -O1 -fno-inline \
 -I- -I. -Iada -I../../gcc/ada ../../gcc/ada/a-except.adb -o ada/a-except.o
+===========================GNAT BUG DETECTED==============================+

| Error detected at a-except.adb:1305:1                                    |

# athlon + amd64:

   -gnatpg -gnata -g -O1 -fno-inline \

raised STORAGE_ERROR : stack overflow (or erroneous memory access)
make[2]: *** [ada/a-except.o] Error 1


with patch from http://gcc.gnu.org/ml/gcc-patches/2005-07/msg01666.html
after manual merge (due to 1 reject):

# ppc:

../../xgcc -B../../ -c -O2 -ggdb -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes       -gnatpg -gnata -I- -I../rts -I.
