When i try to compile the libsupc++ , cc1plus give a segfault error on the compilation of del_op.cc file.
This makes impossible to bootstrap the compiler with -fdump-translation-unit turned on.
I've reported here the output of the 2 compilation i made:

>How-To-Repeat:
Build the tree-ssa branch from cvs.
Then try the following compilation (adjust the path to just built cc1plus ) from the ./i686-pc-linux-gnu/libstdc++-v3/libsupc++ directory :
/CurrentWorks/cvs/gcc/tree-ssa-branch/gcc/gcc/cc1plus -fpreprocessed del_op.ii -quiet -dumpbase del_op.cc -auxbase-strip del_op.o -g -O2 -Wall -Wno-format -W -Wwrite-strings -Winline -version -fno-implicit-templates -fdiagnostics-show-location=once -ffunction-sections -fdata-sections -fdump-translation-unit -o del_op.s
The same compilation with a cc1plus compiled from the ast-optimizer branch will go fine.
I've attached the del_op.ii file for preprocessing.
