Been a while here... I am getting what appears to be the same crash, mine occurs during the test portion of mvn package. with almost the same module and frame: C [libc.so.6+0x804dc] cfree+0x1c

I have set up for this build on a centos7/oracle JDK8 docker image. GCC version gcc-c++.x86_64 0:4.8.5-16.el7_4.2

The compile completed successfully apart from a few C/C++warnings : warning: comparison between signed and unsigned integer expressions [-Wsign-compare]

Did you ever resolve this issue?

Actually I think I have resolved this following the recommendation over at #29

The master at fastText has moved way past what it was on Nov 7, and the head of master did NOT work for me, however picking up commit c5cb6b2d0e295e58cfa827e38d2e9b1e0cbe09e4 (fasttext commit on Nov7) has gotten the tests to run and mvn package to complete successfully!

Now if we could get a maintainer to check out issue #29 and maybe pull in the fix!

Nope, I used a workaround to wrap it as web service and deployed with docker as back end microservice. And then instead of close the jfastText, I just restart docker container to avoid the jfastText's crash impacts all my application.
