Huge memory usage with current g++ :-( -> endless (?) recursion in walk_tree <expand_call_inline>



Trying to bootstrap gcc from CVS with:
/cvs/gcc/configure --prefix=/opt/gcc-2.96.test --enable-shared --enable-threads \
         --with-gnu-as --with-gnu-ld
on i686-linux (kernel 2.2.16, glibc 2.1.3) I noticed that compiling
libstdc++ lead to an enourmous memory usage (my machine has 256 MB of
main memory and g++ used more than 400 MB).  The problem occurs with
the following command:

echo cstring
cstring
if [ x"-fpic" != x ]; then \
  /builds/gcc/gcc-2.96/gcc/g++ -B/opt/gcc-2.96.test/i686-pc-linux/bin/ -B/opt/gcc-2.9
6.test/i686-pc-linux/lib/ -B/builds/gcc/gcc-2.96/gcc/ -isystem /opt/gcc-2.96.test/i68
6-pc-linux/include -L/builds/gcc/gcc-2.96/i686-pc-linux/libstdc++ -c -g -O2 -fvtable-
thunks -D_GNU_SOURCE -fno-implicit-templates -I/cvs/gcc/libstdc++ -I/cvs/gcc/libstdc+
+/stl -I../libio -I/cvs/gcc/libstdc++/../libio -nostdinc++ -D_IO_MTSAFE_IO -fpic -DC 
\
    `for N in REP MAIN TRAITS ADDSS ADDPS ADDCS ADDSP ADDSC EQSS EQPS EQSP NESS NEPS 
NESP LTSS LTPS LTSP GTSS GTPS GTSP LESS LEPS LESP GESS GEPS GESP; do echo " -D${N}"; 
done` \
    /cvs/gcc/libstdc++/sinst.cc -o pic/cstrmain.o; \
else true ; fi

Using -O1 instead of -O2 fixed this.

After setting ulimit to 128 MB I got:
if [ x"-fpic" != x ]; then \

I'm appending the sinst.ii file.  If anybody has any suggestion how I
could debug it, please tell me.  I've noticed this first at the
beginning of this week but did my last successfull bootstrap before
that around the 15th.
