develop has problem

[kaz7]

Current develop branch has a problem. A compiled program by this may causes segmentation fault.

This problem is introduced by following upstream's modification. So, reverting this fixes the problem. Please do it if you need to fix this problem quickly.

I submit an issue on llvm. And a suggestion, a99cceb, works great. The issue is solved on our develop branch. It will be fixed on upstream's main branch soon.
