Installing libgcj consumes huge amounts of memory

Sat Dec 3 23:35:00 GMT 2005

Is anyone seeing this? With current 4.1 sources, on a machine with "only" 
1GB of main memory + 1GB swap, the following part of `make install`
 Adding java source files from srcdir '/cvs/gcc/trunk/libjava/classpath'.
 Adding java source files from VM directory /cvs/gcc/trunk/libjava /tmp/OBJ-1203-1719/i686-pc-linux-gnu/libjava
 Adding generated files in builddir '..'.
 make -f /cvs/gcc/trunk/libjava/classpath/lib/Makefile.gcj \
 GCJ='/tmp/OBJ-1203-1719/gcc/gcj \
 -B/tmp/OBJ-1203-1719/i686-pc-linux-gnu/libjava/ \
 -B/tmp/OBJ-1203-1719/gcc/' \
 compile_classpath='..:/cvs/gcc/trunk/libjava:/tmp/OBJ-1203-1719/i686-pc-linux-gnu/libjava:/cvs/gcc/trunk/libjava/classpath:/cvs/gcc/trunk/libjava/classpath/external/w3c_dom:/cvs/gcc/trunk/libjava/classpath/external/sax:.:'

 top_srcdir=/cvs/gcc/trunk/libjava/classpath
spawns a recursive make (GNU make 3.80) that consumes some 450MB of memory 
and triggers a system load of 12+, basically rendering the machine dead 
for about a minute.
On a different machine with only 512MB + 1GB swap, this time running 
FreeBSD 5.3, I cannot install GCC any longer.
This seems to be a regression between the 20051125 and 20051202 snapshots
of GCC 4.1, but I failed to find any indications in the Makefiles, so the
problem may a bit older.
Any ideas how I could nail this down? Anyone else seeing this?
