Hello,
The SQLite library is crashing in icuOpen() function because it is trying to
check the strlen of a string, which is NULL. I have also put the stack trace.
In this case zInput is NULL. And so it is crashing in this line: nInput =
strlen(zInput);
Here is the partial function definition of icuOpen().
static int icuOpen(
sqlite3_tokenizer *pTokenizer, /* The tokenizer */
const char *zInput, /* Input string */
int nInput, /* Length of zInput in bytes */
sqlite3_tokenizer_cursor **ppCursor /* OUT: Tokenization cursor */
){
IcuTokenizer *p = (IcuTokenizer *)pTokenizer;
IcuCursor *pCsr;
const int32_t opt = U_FOLD_CASE_DEFAULT;
UErrorCode status = U_ZERO_ERROR;
int nChar;
UChar32 c;
int iInput = 0;
int iOut = 0;
*ppCursor = 0;
if( nInput<0 ){
nInput = strlen(zInput);///Crashes here because zInput is NULL///
}
nChar = nInput+1;
.
.
.
.
.
.
.
