-qemu-mipsn32el user mode emulator allocates pointers beyond upper memory limit
-Description of problem:
-In qemu-based N32 mips chroots (both BE and LE), I became aware of memory-intensive programs segfaulting, apparently at random. tar, gcc, but only in specific situations. Watching the strace output of gcc, I got the impression that it happens when memory beyond 2Gbyte is allocated. (mips n32 and o32 uses only 31 bit of a pointer, I've been told, so this is somewhat expected, but a segfault is nevertheless wrong.) 
-
-So, I used the following test program, statically linked:
-```
-#include <stdlib.h>
-#include <stdio.h>
-#include <string.h>
-
-int main() {
-
-  char *pointer;
-  int i;
-
-  for (i=1; i<301; i++) {
-
-    printf("Allocation %i : ", i);
-    pointer = malloc(20480000 * sizeof(char));
-
-    printf(" pointer is %p, ", pointer);
-
-    if (! pointer) {
-      printf("malloc failed\n");
-      exit(0);
-    };
-
-    memset(pointer, 0xDB, 20480000);
-    printf(" filled\n");
-  }
-};
-```

-With mips3 n32 I get the following output:
