Bug ID: 80486
Summary: spurious -Walloc-size-larger-than and
-Wstringop-overflow in dominance.c during
profiledbootstrap
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
A profiledbootstrap on powerpc64le and x86_64 shows a bunch of
-Walloc-size-larger-than and -Wstringop-overflow warnings that don't show up
otherwise. They also don't show when the C++ new expression the former
warnings point is replaced with the libiberty XCNEWVEC and XNEWVEC macros.
