*** Error in `../ReSampler': double free or corruption (out): 0x0000000001a7edc0 ***              

Update 24/02/18:
fixed channel output buffer size out-by-one bug.
See attached valgrind output
valgrind-session-ReSampler-bug.txt

Update 17/02/18: crashing as soon as
std::vector<std::vector> outputChannelBuffers;
is destroyed. Still not exactly sure why.
