--- Comment #33 from H.J. Lu <hjl.tools at gmail dot com> --- There are many calls to _ZmlRK10ggSpectrumS1_ in LTO IR. Some calls have parameters with unknown alignment. But they are ignored by IPA-CP, which applies parameter alignment from calls with known parameter alignment. When _ZmlRK10ggSpectrumS1_ is called from callers with 8-byte parameter alignment, it crashes.
