Segfault with ApproximateProgressiveMorphologicalFilter

Environment

• Operating System and version: Ubuntu 16.04
• PCL Version: 1.8
• Eigen 3

Description

I'm trying to use ApproximateProgressiveMorphologicalFilter, but I have a Segmentation Fault at line 128 of approximate_progressive_morphological_filter.hpp

127 Eigen::MatrixXf A (rows, cols); 
128 A.setConstant (std::numeric_limits<float>::quiet_NaN ());

During the execution of the code, I cout rows and cols :

rows : 94
cols : 166

Here is the valgrind logs :

Anyone can help ?

Most likely the same issue as #1684, #1791, #2013. Should be resolved by #2100, please re-open if not.
