Segmentation Fault Creating KDTreeIndexParams

[mattangus]

I'm getting a seg fault from this line of code:

auto temp = flann::KDTreeIndexParams(4);

Here is the stack trace:

received signal SIGSEGV, Segmentation fault.
0x00007fff23df5616 in flann::any::reset (this=0xdb46330) at ..../flann/src/cpp/flann/util/any.h:263

Any ideas what is going wrong?

I will work on making a minimal example and post back here.

@mattangus meet the same segmentaion fault when using pcl with kdtree, the stack is almost the same, have you fixed this problem?

[mattangus]

Unfortunately not :(

Got stuck in this creepy problem for one week, finally use nanoflann instead. But lots of algorithms in pcl still rely on flann, need help for this bug....
