Version: 15.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: gjl at gcc dot gnu.org

{
return 0;
}
Produces the bus error below on cfarm216 build=host=sparc-sun-solaris2.11
$ avr-ld --version
GNU ld (GNU Binutils) 2.45
Apart from -flto, the compiler seems to work ok.
