We are upgrading an LLVM 4.0-based opt module to LLVM 5.0. After the
upgrade our module works when built with an LLVM Debug build, but
with an LLVM Release build we are encountering the following error.
This happens after our passes have successfully run. I believe this has
to do with the way our passes are registered. Would greatly appreciate
some pointers, as to where to look.
Program received signal SIGSEGV, Segmentation fault.
