Bug ID: 86344
Summary: GCC 8.1 ICEd at LTO stage
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: oddin at mimecast dot com
CC: marxin at gcc dot gnu.org
Target Milestone: ---
I have a fairly large C++ project that I build with LTO (including dependencies
that are packaged up in LTO form) which successfully LTOs on GCC6 and Clang6.
However, I get this error when trying it with GCC8.1:
lto1: internal compiler error: in add_symbol_to_partition_1, at
lto/lto-partition.c:203
0x5658ca add_symbol_to_partition_1

Unfortunately I've not yet been able to create a minimal sample and am sadly
not able to provide a dump of everything it's LTOing due to license
constraints.

Compiler arguments passed at build-time are -O3 -flto -fuse-ld=gold (same crash
is produced if I omit the gold linker)
