gcc 4.2.2 fails to compile file on aix 5.2 with "cc1plus: out of memory allocating", works without optimization

[Thomas Mittelstaedt <T.Mittelstaedt@xxxxxxxxxx>]

Hi,

I have trouble compiling a file with optimizations. Without -O2, it 
compiles. gcc 4.1 does compile it with -O2.
I have attached the preprocessed source.


cd /localbuild/source/V9_UNICODE_RESTRUCTURE/3rdparty/Qt/src/script/
make -f Makefile_projects
