internal compiler error in C++ front end

[Joe Buck]

The following program blows up egcs (every version since at least 970910
through the present version):

#include <vector>
vector<int> v(3,5);

I've verified that the crash occurs on both Linux and Solaris/sparc.

The message is

/usr/local/egcs/include/g++/vector.h:103: Internal compiler error 97.
/usr/local/egcs/include/g++/vector.h:103: Please submit a full bug report
to `egcs-bugs@cygnus.com'.

vector<double> v(5, 3.0);

works fine.

vector<double> v(3.0, 5);

is quietly accepted, but seems bogus.  I suppose the compiler can
assume InputIterator == double, but this seems strange.

does not crash, but

vector<double> v(3, 5);

does: so does the illegal
vector<double> v(3.0, 3.0);

It seems that there is some confusion between vector<T>(size_type,const T&)
and the template member vector<T>(Iterator,Iterator).  The odd thing
is that for vector<int>(32,3) the second seems in some ways a better match,
but STL is banking on the first one being chosen! (to get a vector of
32 elements with value 3).

While it's likely that this particular case would not have been
caught, this does suggest that the libstdc++ tests are too weak; tvector
does not try out even 1/10 of the vector class functionality.  Tests that
at least call each method of vector (and the other STL classes) at least
once would be a great help.  (Perhaps others already have something: the
ObjectSpace free tests seem too weak).
