Dear Maintainer,

The following test case causes a segfault.
The test looks similar to the one in bug #871667, but the
backtrace differs in a way that suggests that it's a
different bug.


#include <stdio.h>
#include <string.h>
#include <stdlib.h>

#include "unicode/ustring.h"
#include "unicode/utypes.h"
#include "unicode/ucol.h"


int main()
{
  UCollator *coll;
  UCollationResult result;
  UErrorCode status = U_ZERO_ERROR ;

  const char *loc = "az-Latn-AZ";
  const char *s1 = "ab";
  const char *s2 = "abc\xf0\x9f\x98\x87";

  coll = ucol_open(loc, &status);
  if (U_FAILURE(status)){
    fprintf(stderr, "ucol_open failed\n");
    exit(1);
  }

  /* segfaults with libicu 52.1-8+deb8u5 */
  result = ucol_strcollUTF8(coll,
                            s1, strlen(s1),
                            s2, strlen(s2),
                            &status);

  return 0;
} 

Result:

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff78c2030 in ucol_getLatinOneContractionUTF8 (
