gcc 4.0.1 Memory error during make on AIX 5.0.0.8 using gcc 3.3.3

[AIX_DOS_OS2]

Hi,
   Any one have any idea why I am getting the following error exit?

/usr/local/bin/gcc   -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING -DIN_GCC   -W -Wall

make[1]: Leaving directory `/tmp/GCC/Source/BuildDir/gcc'
make: *** [bootstrap] Error 2

   I have tried running "make" over 6 times and keep getting this message.
   I have no idea what is going on.
   As far as I can tell I have unlimited stack space and such.
I am running this build as root.  I am using the following "configure"
and "make" calls.  I have altered the configure calling parameters with no
change in the end result.  My last attempt was to add the line beginning
--with-cpu... in the configure and by removing -lean from the bootstrap
parameter in the make.

/tmp/GCC/Source/gcc-4.0.1/configure --disable-nls --with-libiconv-prefix=/usr \
       --enable-language=c,c++,f95,objc --disable-shared --disable-multilib --enable-threads=aix \
       --with-cpu=power4 --with-system-zlib

make CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap-lean

Bye,

Problem compiling gcc 4.0.1 on AIX 5.0.0.8

[AIX_DOS_OS2]

Help!
   I am unable to compile gcc 4.0.1 on AIX 5.0.0.8 because:

"out of memory allocating 80016 bytes after a total of 4161652492 bytes"

This message appear while executing the following commands:
           ********************* configure ************************
/mkcd/GCC/Source/gcc-4.0.1/configure --disable-nls --with-libiconv-prefix=/usr

This is the last section section of output from make before it error exits:

   I do not know what this output from make means:
	build/genattrtab /mkcd/GCC/Source/gcc-4.0.1/gcc/config/rs6000/rs6000.md > tmp-attrtab.c

   Can't imagine what it would be creating that is so large! :(

   Any assistance would be GREATLY appreciated!

Dwight

	This specific case is mentioned in the "Host/Target specific
installation notes for GCC" section on AIX:

out of memory bootstrap failures may indicate a problem with process
resource limits (ulimit). Hard limits are configured in the
/etc/security/limits system configuration file.


	On AIX, root has resource limits like every other user.  Make sure
that you are viewing the hard limits, not the soft limits.  I suspect that
the hard limits are capped.  Stack, data, and memory need to have large
limits to bootstrap GCC.  Also, building as root probably is not a good
idea.

	By the way, the 4161652492 does not represent the total amount of
memory currently allocated, some of the memory has been returned during
the process execution.

	I also would recommend not changing the Make options.
