Hello,
some additions:

The same happens for genautomata.c.

/opt/freeware/src/packages/BUILD/gcc-build/./prev-gcc/xgcc -B/opt/freeware/src/packages/BUILD/gcc-build/./prev-gcc/ -B/opt/freeware/powerpc-ibm-aix5.3.0.0/bin/ -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros                                     -Wno-overlength-strings    -DHAVE_CONFIG_H -DGENERATOR_FILE -I. -Ibuild -I../../gcc-4.3.2/gcc -I../../gcc-4.3.2/gcc/build -I../../gcc-4.3.2/gcc/../include -I../../gcc-4.3.2/gcc/../libcpp/include  -I../../gcc-4.3.2/gcc/../libdecnumber -I../../gcc-4.3.2/gcc/../libdecnumber/dpd -I../libdecnumber -I/opt/freeware/include   -o build/genautomata.o ../../gcc-4.3.2/gcc/genautomata.c

gmake[3]: *** [build/genautomata.o] Error 1


I have successfully tried to produce the preprocessed output with -E. This worked OK. 

After that I could compile the two preprocessed files with 4.2.4 gcc -c xxx.c ... With 4.3.2 gcc the same error happens:

export PATH=/opt/freeware/src/packages/BUILD/gcc-build/prev-gcc:$PATH;xgcc  -c insn-attrtab.prep.c

Please submit a full bug report,

I will upload the two files.

Can you try increasing the stack size limit when building?  insn-attrtab.c compiled at -O0 is known to have a big stack size.

Hello,
OK, I will rebuild with a doubled stack size.
I will report back as soon as I have new results.

If I produce the preprocessed listing with -E the I can compile this with gcc 4.2.4.

Hello,
any news ?

Maybe you are running out of native heap. Try with something like:

export LDR_CNTRL=MAXDATA=0x40000000

Hello,
OK, I will try with an extended heap.

  Rainer

Hello,
It works for me, to bootstrap GCC 4.3.3 on AIX 5.3

Hello,
OK I will try gcc 4.3.3.

Please could you be so kind and post your complete configure call + additional env settings (if set) ?

Thanks in advance.

Bye
  Rainer

Hello,
I configured with:
../gcc-4.3.3/configure --prefix=/usr/local/4.3.3 --enable-shared --enable-threads=posix --enable-checking=release --enable-__cxa_atexit --disable-libunwind-exceptions --enable-languages=c,c++,objc
Additional env sets:
CC=cc (I used the native compiler)
LDR_CNTRL=MAXDATA=0x40000000
CONFIG_SHELL=.../bash

vladimir penev
