HI, all

   My daemon exists a libvirt API  call:

virEventRegisterDefaultImpl();

once I called the virEventRegisterDefaultImpl() ,must be core ,the bt stack is:

(gdb) bt
#0  free (ptr=0x1) at include/jemalloc/internal/arena.h:652
#1  0x00007f57690a488a in virFree () from /lib64/libvirt.so.0
#2  0x00007f57690c3562 in virResetError () from /lib64/libvirt.so.0
#3  0x00007f57690c49ad in virEventRegisterDefaultImpl () from /lib64/libvirt.so.0
#4  0x00000000004029ad in main (argc=<optimized out>, argv=<optimized out>) at vnf_mgt/vnf_control.c:2920
(gdb) quit

the following code copy from libvirt/src/util /

int virEventRegisterDefaultImpl(void)
{
    VIR_DEBUG("registering default event implementation");

    virResetLastError();

    if (virEventPollInit() < 0) {
        virDispatchError(NULL);
        return -1;
    }

    virEventRegisterImpl(virEventPollAddHandle,
                         virEventPollUpdateHandle,
                         virEventPollRemoveHandle,
                         virEventPollAddTimeout,
                         virEventPollUpdateTimeout,
                         virEventPollRemoveTimeout);

    return 0;
}

void
virResetLastError(void)
{
    virErrorPtr err = virLastErrorObject();
    if (err)
        virResetError(err);
}

static virErrorPtr
virLastErrorObject(void)
{
    virErrorPtr err;
    err = virThreadLocalGet(&virLastErr);
    if (!err) {
        if (VIR_ALLOC_QUIET(err) < 0)
            return NULL;
        if (virThreadLocalSet(&virLastErr, err) < 0)
            VIR_FREE(err);
    }
    return err;
}

void
virResetError(virErrorPtr err)
{
    if (err == NULL)
        return;
    VIR_FREE(err->message);
    VIR_FREE(err->str1);
    VIR_FREE(err->str2);
    VIR_FREE(err->str3);
    memset(err, 0, sizeof(virError));
}

# define VIR_FREE(ptr) virFree(1 ? (void *) &(ptr) : (ptr))

void virFree(void *ptrptr)
{
    int save_errno = errno;

    free(*(void**)ptrptr);
    *(void**)ptrptr = NULL;
    errno = save_errno;
}

when my daemon link with jemalloc must core£¬but if i use glibc to manage memory ,then it work fine, why ?
