Caffe "make runtest" error

[mz3220]

Hello
First of all
Caffe users list is a dead place. No responses there at all!!

I try to build a custom version of CPU-only Caffe. However, "make runtest" results in this error:

1 test from MultiSoftmaxLossLayerTest/0, where TypeParam = caffe::FloatCPU
[ RUN ] MultiSoftmaxLossLayerTest/0.TestGradient
F0923 03:04:42.193163 26424 layer.hpp:362] Check failed: ExactNumTopBlobs() == top.size() (3 vs. 2) MULTI_SOFTMAX_LOSS Layer produces 3 top blob(s) as output.
*** Check failure stack trace: ***
here 10 lines of @ random numbers
Aborted (core dumped)
make: *** [Makefile:416: runtest] Error 134

Please I would appreciate your help.
