Reasonable question. I often bootstrap GCC and then try a whole 
series of simple tests *after* I run the whole testsuite. To be
honest I had not seen an ICE before and was surprised to see it.

As for -mptr64, well yes it was a dumb idea. Given that it isn't
documented anywhere.

At least it does not seem to exist anywhere here : 

    https://gcc.gnu.org/onlinedocs/gcc-4.7.4/gcc/

Some of the little tests I run involved posix thread dispatch 
tests as well as slogging memory around and some are simple 
floating point performance tests. I look at the output assembly
from both GCC and Oracle Studio tools. There really is not
much of a performance gap anymore unless you are in possession
of a Sparc T5 or some server with 256 processor cores. 

Regardless, looks like a red herring :
