Re: [mosquitto-dev] Memory Leak problem

[Roger Light <roger@xxxxxxxxxx>]

Hi Elvis,

You're right, this can happen. This is fixed in the 1.4 branch, but
unfortunately was missed out of 1.3.4. I would suggest just not using
a leading slash for the moment, or trying out the 1.4 code.

Cheers,

Roger
