Bug ID: 91028
Summary: g++.dg/lto/alias-2 FAILs with -fno-use-linker-plugin
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: hubicka at gcc dot gnu.org, marxin at gcc dot gnu.org
Target Milestone: ---
Target: sparc-sun-solaris2.11, i386-pc-solaris2.11,
x86_64-pc-linux-gnu
The new g++.dg/lto/alias-2 test FAILs on Solaris/SPARC and x86:
+FAIL: g++.dg/lto/alias-2 cp_lto_alias-2_0.o-cp_lto_alias-2_1.o execute -O2
-flto
The same failure happens on Linux/x86_64 when using -fno-use-linker-plugin
(which matches the Solaris case):
Program received signal SIGABRT, Aborted.

This is the third such case after PR ipa/90720 and PR lto/89884. It seems
something fundamental is amiss here.
