Bug ID: 253716
Summary: LTO seems to be broken in 13-BETA3
Product: Base System
Version: 13.0-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
My software build system's been using LTO for builds for years now.
I append "-flto=thin -ffat-lto-objects -fuse-linker-plugin
-Wl,--thinlto-jobs=8" to CFLAGS/CXXFLAGS and it worked nicely until 13-BETA1
(last tested one).
Yesterday I updated to 13-BETA3, and same options now cause linker issues.
Example for Make 4.3:

(it also breaks with fat LTO enabled, not only with Thin)
It builds fine if I just remove "-flto" option.
