Bug ID: 80612
Summary: ICE compiling grep-3.0 and m4-1.4.18 with LTO
Product: gcc
Version: 7.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: sven.c.dack at sky dot com
Target Milestone: ---
Both grep-3.0 and m4-1.4.18 show the same error message, because they both make
use of the same source file "obstack.c".

The ICE occurs in the final link optimization of the executables. Both packages
were configured as follows:
CFLAGS="-pipe -O3 -march=native -fomit-frame-pointer -fno-builtin-memcmp
-fipa-pta -flto -ffat-lto-objects -flto-partition=one"
LDFLAGS="-Wl,-O1,--hash-style=gnu,--enable-new-dtags,-z,combreloc,-z,noexecstack,-z,relro,-z,now
-pipe -O3 -march=native -fomit-frame-pointer -fno-builtin-memcmp -fipa-pta
-flto -ffat-lto-objects -flto-partition=one -fuse-linker-plugin"
../grep-3.0/configure --prefix=/home/sven/test
make -j24 all
...
Compiler version is:
gcc --version
gcc (GCC) 7.1.1 20170502
