Segfault in


I am attempting to build the MXNet library for an embedded ARM system but am having some issues validating the build.
I built the library with the following options as I was trying to build a minimal footprint library. I will not be doing any image recognition or GPU.


I built both the library and the python bindings using Buildroot but the library seg faults when trying to import the MXNet module into Python.
I hooked up GDB to Python to better understand what was seg faulting and got the following stack trace:

$ export MXNET_LIBRARY_PATH=/usr/lib/ && gdb python

Python 2.7.15 (default, Jul 31 2018, 19:39:18)

Type "help", "copyright", "credits" or "license" for more information.
>>> import mxnet

Program received signal SIGSEGV, Segmentation fault.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

I don’t know if I missed some options when building libc or if I need to disable some options when building MXNet but was wondering if anyone in the community had thoughts/insights into what might be going wrong.
