Stack dump:
0.	Program arguments: llvm-mctoll -d a.out 
Aborted

I cloned all llvm,clang,mctoll source today, make sure they are newest and master, but still has aborted crash, it really hurts.

a.out is just a compiled helloworld.
gcc version 4.8.5, centos7

cat a.out | base64

you can decode and have a test.

Thanks for trying out the tool.

As noted in README.md, at present development and testing is being done using Ubuntu 18.04. It is expected that build and test would work on Ubuntu 16.04, 17.04 and 17.10.

Support for codegen and/or ELF binary packaging differences on CentOS 7 needs to be added.

try on ubuntu compiled a.out, it works!
but hope you can support centos bin anyway.
thanks!
