>-ftemplate-depth=100

This is not a bug, the whole point of template-depth is to prevent the crashes
like this from happening.


Anyways clang on the trunk says:

:15:9: warning: stack nearly exhausted; compilation time may suffer,
and crashes due to stack overflow are likely [-Wstack-exhausted]
typeof( ft< F, n-1 >( F(), 0 ) )
^
...

:15:9: fatal error: recursive template instantiation exceeded maximum
depth of 1024
typeof( ft< F, n-1 >( F(), 0 ) )
^

I tried  ulimit -s unlimited. This time, the error messages are as follows:

g++ -ftemplate-depth=100 test.cpp

Yes but that seems to be because GCC goes into an infinte recursive
instantiation, which it shouldn't do.
