Compiling "libgomp.c++/task-4.C" with "g++" is successful, but compiling it with "g++ -fopenmp" gives:

libgomp.c++/task-4.C: In function 'void foo(int, int)':
libgomp.c++/task-4.C:37: error: type mismatch in indirect reference
int[0:D.2193]

int[0:<<< error >>>]

D.2218 = &(*q.1)[0];

libgomp.c++/task-4.C:37: error: type mismatch in indirect reference
int[0:D.2173]

int[0:<<< error >>>]

D.2219 = &(*p.0)[0];

libgomp.c++/task-4.C:37: internal compiler error: verify_stmts failed


(It might be not a true regression but a side effect of stricter type checking in 4.5.)
