Package: g++-3.3
Version: 1:3.3.3-7
Severity: serious
Justification: Causes other packages to FTBFS

With 1:3.3.3-6 (no bug) or -7 (bug):

# apt-get build-dep povray-3.5
$ apt-get source povray-3.5
$ cd povray-3.5-3.5.0c/src
$ i386-linux-g++  -DPREFIX=\"/usr\" \

	-Wno-multichar -MT bezier.o         -MD -MP -MF ".deps/bezier.Tpo" -c -o \
	bezier.o bezier.cpp

If -6, if succeeds, if -7, it fails with this output:

| bezier.cpp: In function `void bezier_bounding_sphere(double
| (*)[4][4][3],
|    double*, double*)':
|    bezier.cpp:859: internal compiler error: Segmentation fault
| Please submit a full bug report,

| See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Note that I couldn't get -save-temps to trigger the same error.
