           Summary: undefined array size inside struct  cause segfault with
                    -g
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: eranian@hpl.hp.com
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: gcc version 3.4 20030507 (experimental)
  GCC host triplet: ia64-hp-linux
GCC target triplet: ia64-hp-linux

If you compile the following code sequence as follows:

/opt/gcc-pre3.4/bin/gcc -Wall -c -O2 test.c -g
test.c:2: error: `HASH_SIZE' undeclared here (not in a function)
test.c:3: internal compiler error: Segmentation fault
Please submit a full bug report,

% cat test.c
typedef struct {
	int fd_hash[HASH_SIZE];
} pfmon_task_worker_t;


If you drop -g, it works. If the array is declared outside of the struct
you get the expected error message.
