I think the problem is the "free" in this function:
JNIEXPORT jint JNICALL Java_org_sqlite_NativeDB_bind_1text(
JNIEnv *env, jobject this, jlong stmt, jint pos, jstring v)
{
const char *chars = (*env)->GetStringUTFChars(env, v, 0);
return sqlite3_bind_text(toref(stmt), pos, chars, -1, free);
}
In JNI, as far as I know, you must release memory returned from
GetStringUTFChars() with ReleaseStringUTFChars(), not free().
Try this (untested, never compiled):
JNIEXPORT jint JNICALL Java_org_sqlite_NativeDB_bind_1text(
JNIEnv *env, jobject this, jlong stmt, jint pos, jstring v)
{
const char *utf = (*env)->GetStringUTFChars(env, v, 0);
int rc = sqlite3_bind_text(toref(stmt), pos, utf, -1,
SQLITE_TRANSIENT);
(*env)->ReleaseStringUTFChars(env, v, utf);
return rc;
}
With any luck, this should avoid the crash.
