[Question][Hw3] Segmentation fault

[kws1207]

I inserted my own instruction while iterating each instructions, and returned llm itself.

Then, make succeed but ./sanitizer test/example1.ll produces an error: Segmentation fault (core dumped).

What can be possible reasons, and is there any tips to do debugging in this case?

Any kind of help would be appreciated.

Just putting print function at possibly flawed point can be easy way to catch bugs.
