I just tried to compile the package normaliz-2.2
with the C++ compiler version 4.5 snapshot 20100311 and it said
vector_operations.cpp: In function 'std::vector<long int> v_make_prime(const
std::vector<long int>&, Integer&)':
vector_operations.cpp:300:17: error: statement marked for throw in middle of
block
# .MEM_36 = VDEF <.MEM_81>
D.34201_8 = v_gcd (v_2(D));
vector_operations.cpp:300:17: internal compiler error: verify_stmts failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Preprocessed source code attached. Flags -O2 -floop-parallelize-all required.

Reduced testcase:
struct vector
{
long &operator[](int __n) { return *(_M_start + __n); }
~vector();
long *_M_start;
};
long v_gcd();
void v_make_prime(vector& v,long& g, long j){
int i;
vector w;
g=v_gcd();
for (i = 0; i < j; i++)
w[i]=v[i]/g;
}
