Phil,

netwinder.org seems to have made it into ORBS.  Could you pass this on to the
gcc list for me while I get that straigbtened out.

I've been unable to build the mainline on a NetWinder for the last two daysd. 
CPP segfaults during the bootstrap.  I configured with:
CFLAGS="-g -O0" ../gcc-2.96/configure --with-cpu=strongarm --enable-shared.
and did a 
make bootstrap-lean

do \
  echo ${name}; \
  ./xgcc -B/usr/local/armv4l-unknown-linux-gnu/bin/ -B./ -isystem
/usr/local/armv4l-unknown-linux-gnu/include -O2   -DIN_GCC    -g -W -Wall
- -Wtraditional -isystem ./include  -fomit-frame-pointer -fPIC -g0
- -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED   -I.

- -I../../gcc-2.96/gcc/../include -c -DL${name} \
       ../../gcc-2.96/gcc/libgcc2.c -o ${name}.o; \
  if [ $? -eq 0 ] ; then true; else exit 1; fi; \
  ar  rc tmplibgcc2.a ${name}.o; \
  rm -f ${name}.o; \

cpp: memory violation at pc=0x4006ff54, lr=0x02073eb0 (bad 
address=0x0207471c, code 0)
xgcc: Internal compiler error: program cpp got fatal signal 11

To date I have not had any success in debugging this problem.  cpp is failing in
chunk_alloc in libc.  The return address (lr) and the bad address are way
outside the valid range for code and data for cpp.  I have not been able to get
the CPP command to run from the prompt or gdb.  I always get:

/bin/bash: -c: line 1: syntax error near unexpected token `-Asystem(u'
/bin/bash: -c: line 1: `exec /home/scottb/cvstree/gcc-2.96-build/gcc/./cpp

I'm using bash 2.04 ATM.  I've also tried 2.03.

Program exited with code 02.
You can't do that without a process to debug.
(gdb)

Does anyone have a suggestion about how to get around this so I can investigate
further?  Any pointers or tips would be appreciated.
