--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
So it's really problem as with LTO we don't put the large array into .lbss
section:
LTO:
.file "<artificial>"
.text
.local a
.comm a,2830270464,32
.local b
.comm b,4,4
non-LTO mode:
.globl a
.section .lbss,"aw"
.align 32
.type a, @object
.size a, 2830270464
a:
.zero 2830270464
So the symbol goes from .lbss section to .data section as LTO makes the symbol
local.
