           Summary: internal compiler error: in change_address_1, at
                    emit-rtl.c:1954
           Product: gcc
           Version: 4.4.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: brian.davis@eclipseoptions.com


NOTE: changing the typedef of ITERATOR_TYPE from uint32_t to uint16_t on line
903 of the preprocessed source will allow the program to compile successfully.

Not sure why it didn't get attached before, but perhaps I uncompressed it on my
local file system after setting the path but before submitting the bug and
didn't check the results carefully.  Anyway, now attached.

Confirmed.  Works on 4.6 and 4.7.  Reduced testcase:

typedef unsigned char uint8_t;
typedef unsigned int uint32_t;
typedef uint32_t ITERATOR_TYPE;
const uint8_t RETIRED = (1 << 1);
struct AQMRU_Instantiated_For_Payload {
    ITERATOR_TYPE next;
    uint8_t flags;
};
typedef struct {
    ITERATOR_TYPE queueHead;
    ITERATOR_TYPE queueCount;
    ITERATOR_TYPE stackHead;
    struct AQMRU_Instantiated_For_Payload entries[((1 == sizeof(ITERATOR_TYPE))
? (255) : ((2 == sizeof(ITERATOR_TYPE)) ? (65535) : ((4 ==
sizeof(ITERATOR_TYPE)) ? (4294967295U) : 0)))];
} TestQueue;
int main(int argc, const char *argv[])
{
  TestQueue testQueue;
  ITERATOR_TYPE iter;
  ITERATOR_TYPE count;
  for (count = 0;
       count < ((1 == sizeof(ITERATOR_TYPE)) ? (255) : ((2 ==
sizeof(ITERATOR_TYPE)) ? (65535) : ((4 == sizeof(ITERATOR_TYPE)) ?
(4294967295U) : 0)));
       ++count)
    {
      ITERATOR_TYPE temp = iter;
      iter = testQueue.entries[iter].next;
      testQueue.queueHead = iter;
      testQueue.queueCount--;
      if (0 == testQueue.queueCount)
        {
          ((((1 == sizeof(ITERATOR_TYPE)) ? (255) : ((2 ==
sizeof(ITERATOR_TYPE)) ? (65535) : ((4 == sizeof(ITERATOR_TYPE)) ?
(4294967295U) : 0))) == testQueue.queueHead) ? (void) (0) : __assert_fail ());
        }
      testQueue.entries[temp].next = testQueue.stackHead;
      testQueue.stackHead = temp;
    }
}

notice the large variable testQueue.
