Problems Building 7.0-Beta3 with -Os

[Jan Lentfer]

Dear List,

I am having problems compiling 7.0-Beta3 on my VIA C7 system with 1 GIG 
of RAM.
The problem seems to be the memory consumption so I turned off all 
larger processes. This is what happens:

===> gnu/usr.bin/cc/libdecnumber (all)
===> gnu/usr.bin/cc/cc_int (all)
cc -Os -pipe -DIN_GCC -DHAVE_CONFIG_H 
-DPREFIX=\"/usr/obj/usr/RELENG_7/src/tmp/usr\" 
-I/usr/obj/usr/RELENG_7/src/tmp/usr/RELENG_7/src/gnu/usr.bin/cc/cc_int/../cc_tools 
-I/usr/RELENG_7/src/gnu/usr.bin/cc/cc_int/../cc_tools 
-I/usr/RELENG_7/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcc 
-I/usr/RELENG_7/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcc/config 
-I/usr/RELENG_7/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcclibs/include 
-I/usr/RELENG_7/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcclibs/libcpp/include 
-I/usr/RELENG_7/src/gnu/usr.bin/cc/cc_int/../../../../contrib/gcclibs/libdecnumber  
-I/usr/obj/usr/RELENG_7/src/tmp/legacy/usr/include -c 
../cc_tools/insn-attrtab.c

Compliation works while only using "-O" optimization level. -O2 and -Os 
both break with this. It used to work in 6.2, though.

This is the output of vmstat 1:
