Bug ID: 126893
Summary: [17 regression] LTO bootstrap failure (lto1: fatal
error: LTO_symtab_tags out of range: Range is 0 to 6,
value is 44)
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: build, lto
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
Target Milestone: ---
LTO bootstrap fails for me at the very end, when libtool relinks during
installation (which is very unfortunate with LTO, see
https://bugs.gnu.org/72613):

I last built r17-3209-g2d3a1b441aad04 fine. I will debug it more tomorrow or
early in the week.
