Template crash with 20/03/00 snapshot and -O2

[Marc Poinot <Marc dot Poinot at onera dot fr>]

The version of GCC: 2.96 (snapshot March, 20th)
The platform: SGI IRIX 6.5 (ABI 64)
Gcc has been compiled which 2.95.1 then with itself.

When compiling with option -O2 there is an internal error.
The compilation is successful with either:

gcc 2.95.1 and -O2
gcc 2.96   without -O2

The preprocessed file has been refused by your mailer,
its size is 300Kb. Let me know if you want it.

The output of the compiler is attached as log

Thanks for your work,
Regards.
