code reproducing the issue, and assembly both with and without -fno-plt
See the attached example program and generated assembly.
Using -fno-plt seems to mess up the stack frame, I cant really pinpoint the
issue and when its triggered, values just point to wrong places.
My system is debian buster x86_64, with clang++ being:
clang version 7.0.0-6 (tags/RELEASE_700/final)
(This is potentially a duplicate of 39252)</pre>
