Hello everybody,
I'm facing a strange issue and believe that my setup is somehow wrong. From
time to time my program crashes with segfault when calling:
if (sqlite3_exec (db, "BEGIN TRANSACTION", 0, 0, 0) != SQLITE_OK)
{
//error
}
The stacktrace points to this function:
static void pthreadMutexEnter(sqlite3_mutex *p){
assert( p->id==SQLITE_MUTEX_RECURSIVE || pthreadMutexNotheld(p) );
#ifdef SQLITE_HOMEGROWN_RECURSIVE_MUTEX
{
pthread_t self = pthread_self();
if( p->nRef>0 && pthread_equal(p->owner, self) ){
p->nRef++;
}else{
pthread_mutex_lock(&p->mutex);
assert( p->nRef==0 );
p->owner = self;
p->nRef = 1;
}
}
#else
/* Use the built-in recursive mutexes if they are available.
*/
pthread_mutex_lock(&p->mutex); //!HERE IT GETS a SEGFAULT!
#if SQLITE_MUTEX_NREF
assert( p->nRef>0 || p->owner==0 );
p->owner = pthread_self();
p->nRef++;
#endif
}
Any ideas why this happens, or how I could workaround the issue? The query
works like 300 times and then suddenly crashes, I checked this with version
3.6.22 (as library) and the actual sources (3.7.8 _ 3007008).
Best regards,
Chris.
