Missing separate debuginfos, use: debuginfo-install glibc-2.17-105.el7.x86_64 libgcc-4.8.5-4.el7.x86_64 libstdc++-4.8.5-4.el7.x86_64 zlib-1.2.7-15.el7.x86_64 (gdb) bt

after debugging it, it seemed that crashing at this line. char h=NULL, hash=NULL h = InitNfiq2(&hash); entered InitNfiq2, but never returned.

You don't need dlsym, link the library instead. Works as expected.

Additionally, the C API is not supported, per the pre-processor definition that you have to set in order to build anything linking against this library. As I've said in your other closed issues, please do not use it. Closing this issue as a result.
