mesh advertiser crash when calling advertiser_packet_discard

[bart]

Hi, I'm getting a crash when discarding an advertising packet.

Roughly what I do is:

// Setup
advertiser_instance_init(_advertiser, NULL, _buffer, MESH_ADVERTISER_BUF_SIZE);
advertiser_address_set(_advertiser, &address);
advertiser_interval_set(_advertiser, intervalMs);
advertiser_tx_power_set(_advertiser, txPower);
advertiser_enable(_advertiser);

// Advertise packet
_advPacket = advertiser_packet_alloc(_advertiser, 7 + ibeacon->size());
_advPacket->config.repeats = ADVERTISER_REPEAT_INFINITE;
advertiser_packet_send(_advertiser, _advPacket);

// Then half a second later, change the packet.
advertiser_packet_discard(_advertiser, _advPacket);
_advPacket = advertiser_packet_alloc(_advertiser, 7 + ibeacon->size());
_advPacket->config.repeats = ADVERTISER_REPEAT_INFINITE;
advertiser_packet_send(_advertiser, _advPacket);

Which crashes at advertiser_packet_discard().

GDB trace:

It looks like packet_buffer_pop() should've been called.

But the mesh advertiser never calls that, as the packet is configured to repeat infinite.

So what would i need to do, in order to change the advertised packet?

Using:

nRF52832

SD 132 6.1.1

SDK 15.3.0

Mesh SDK 3.2.0.

What I do for now, to change the packet, is:

if (_advPacket != NULL) {
    advertiser_disable(_advertiser);
	memcpy(&(_advPacket->packet.payload[7]), ibeacon->getArray(), ibeacon->size());
	advertiser_enable(_advertiser);
	return;
}

This seems to work, but doesn't allow for a change of packet size.
