[Bug c/43995] New: internal compiler error: Segmentation fault on Mips64 crossbuild of ext2progs

[janr at adax dot com]

This happens while building under the T2 SDE environment, which is a framework
for cross building an entire Linux distribution. GCC 4.43 Builds this OK,
switching to GCC 4.5 failes while building the e2fsprogs project.

I tried this with gcc 4.5.0, and the 4.5.1 latest snapshot

The build host is Ubuntu 9.10

The T2 cross compiler info is:

./TOOLCHAIN/tools.cross/crosscc/mips64-t2-linux-gnu-gcc -v
Using built-in specs.

I don't see a way to attach the crc32.i file from this screen, I will see if I
can do it later.
