Bootstrap failures on sparc-unknown-linux-gnu

["Art Haas" <ahaas at airmail dot net>]

Hi.

My builds on my SS20 running Debian have all failed for the last several
days. I was able to build a GCC-3.5 snapshot around July 1 or July 2,
but since then things have failed in while using the stage1 compiler:

stage1/xgcc -Bstage1/ -B/opt/gnu/sparc-unknown-linux-gnu/bin/ -c   -O2
-mcpu=v8 -finline-limit=100000 -DIN_GCC   -W -Wall
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic
-Wno-long-long -Wno-variadic-macros -Wold-style-definition -Werror
-DHAVE_CONFIG_H -DGENERATOR_FILE    -I. -I.

Build goes kaboom at this point.

Machine: SparcStation 20 running Debian

Build configured and build using the following small script:

$ cat cc_conf_script.sh
#!/bin/sh

params="-finline-limit=100000"

CPPFLAGS="-DNDEBUG" \
CFLAGS="-O2 -mcpu=v8 ${params}" \
CXXFLAGS="-O2 -mcpu=v8 ${params} -fno-check-new" \
/opt/build/gcc_3_5_branch/gcc/configure --prefix=/opt/gnu \
--enable-shared --enable-threads=posix --enable-__cxa_atexit
--enable-languages="c,c++,objc" --disable-checking --with-system-zlib

make bootstrap-lean \
BOOT_CFLAGS="-O2 -mcpu=v8 ${params}" \
CXXFLAGS="-O2 -mcpu=v8 ${params} -fno-check-new" > make_out 2>&1

$

Builds on i586-pc-linux-gnu and i686-pc-linux-gnu have worked within the
last two or three days for me.
