Between 20031218 and 20040105, GCC mainline bootstrap (using GCC 3.3.2 as
bootstrap compiler) started to fail in stage 3:

$ stage2/xgcc -Bstage2/ -B/vol/gcc/share/sparc-sun-solaris2.8/bin/ -c -g -O2      -gnatpg -gnata -I- -I. -Iada -I/vol/gnu/src/gcc/gcc-dist/gcc/ada /vol/gnu/src/gcc/gcc-dist/gcc/ada/a-chlat1.ads -o ada/a-chlat1.o -v
Reading specs from stage2/specs
Configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls
Thread model: posix
gcc version 3.4.0 20040105 (experimental)
 stage2/gnat1 -I- -I. -Iada -I/vol/gnu/src/gcc/gcc-dist/gcc/ada -quiet -dumpbase a-chlat1.ads -g -gnatpg -gnata -O2 -mcpu=v7 -gnatO ada/a-chlat1.o /vol/gnu/src/gcc/gcc-dist/gcc/ada/a-chlat1.ads -o /var/tmp//ccBjhVKD.s
+===========================GNAT BUG DETECTED==============================+
| 3.4.0 20040105 (experimental) (sparc-sun-solaris2.8) Constraint_Error SIGSEGV|
| Error detected at a-chlat1.ads:16:23                                     |

This happens even at -O0.  Since it occurs only during stage 3, this is
probably a miscompilation.

Environment:
System: SunOS padouk 5.8 Generic_108528-23 sun4u sparc SUNW,Sun-Fire-880
Architecture: sun4

	
host: sparc-sun-solaris2.8
build: sparc-sun-solaris2.8
target: sparc-sun-solaris2.8
configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls

How-To-Repeat:
Bootstrap GCC on sparc-sun-solaris2.8.

The faulty patch is:

2003-12-31  Mark Mitchell  <mark@codesourcery.com>

	* c-common.c (c_expand_expr): Remove code to return a value
	different from that returned by expand_expr.
	* expr.c (store_expr): Use the validity of a target MEM, rather
	than checking DECL_RTL (exp), to figure out if a copy is
	required.
