>Description:
Compiling the test code (as attached), the compiler 
reports an internal compiler error or crashes: 

Removing TONS of code to get a minimal example made the 
SIGSEGVs vanish; the internal errors remaining: 

gcc -c crashme.cc -Wno-non-template-friend -DBUG=0
crashme.cc: In function `void internal_vect::mult_mv(internal_vect::vector<r>&, 
   const internal_vect::matrix<r, c>&, const
   internal_vect::vector<c>&) [with int r = 10, 
   int c = 10, int N = 3]':
crashme.cc:53:   instantiated from `void 
   vect::operator*=(vect::Vector<R>&, const 
   vect::Matrix<N, N>&) [with int N = 10]'
crashme.cc:89:   instantiated from here
crashme.cc:37: Internal compiler error in c_expand_expr, 
   at c-common.c:3650
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

Similar thing with
gcc -c crashme.cc -Wno-non-template-friend -DBUG=1

(Please don't tell me that I shall make the demo code 
even shorter. I already spent two hours or more to strip 
it down to that size; removing any individual line will 
prevent the bug from showing up.)
>How-To-Repeat:
Compile example code (as attached)

Don't know.
