[Bug 1201048] Re: internal compiler error: in rewrite_use_nonlinear_expr

[Rashad M]

Hello All,

Is this right place to report bugs for gcc 4.7. Its been a long this bug
has been confirmed and no update since then. If I am missing something
else please let me know. If this happens due to some system
configuration or problem in the grass code we could fix it. Asking users
to change from 32bit to 64bit is not something I believe someone would
suggest.
