System: Linux dali.sqx.lde 2.4.9-mosix #17 SMP Sam Sep 1 03:04:51 CEST 2001 i686 unknown
Architecture: i686

>Description:
Duh, sorry: Invalid attachement...

g++ segfaults when it has to processing std::accumulate(begin, end, init, invalid_op) where invalid_op is a invalid template reference.
>How-To-Repeat:
See the attachement for preprocessed code. Here comes the plain code:

$ cat accum.cc
#include<iostream>
#include<numeric>
#include<functional>

int main()
{
    int nums[] = { 1, 2, 3, 4, 5 };
    
    std::cout << std::accumulate(nums, nums + sizeof(nums)/sizeof(*nums),
                                 0, std::plus) << std::endl;
}
$ LC_ALL=C g++ -save-temps accum.cc 
accum.cc: In function `int main()':
accum.cc:10: Internal error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
