            Bug ID: 107327
           Summary: internal compiler error: in tsubst_pack_expansion, at
                    cp/pt.c:12930
           Product: gcc
           Version: 10.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcc
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kaploceh at gmail dot com
  Target Milestone: ---

I'm using GNU Make 4.3 and g++ Configured with:
/builddir/gcc-10.2.1_pre1/configure --build=3Dx86_64-unknown-linux-gnu
--enable-gnu-unique-object --enable-vtable-verify --prefix=3D/usr
--mandir=3D/usr/share/man --infodir=3D/usr/share/info --libexecdir=3D/usr/l=
ib64
--libdir=3D/usr/lib64 --enable-threads=3Dposix --enable-__cxa_atexit
--disable-multilib --with-system-zlib --enable-shared --enable-lto
--enable-plugins --enable-linker-build-id --disable-werror --disable-nls
--enable-default-pie --enable-default-ssp --enable-checking=3Drelease
--disable-libstdcxx-pch --with-isl --with-linker-hash-style=3Dgnu
--disable-sjlj-exceptions --disable-target-libiberty
--enable-languages=3Dc,c++,objc,obj-c++,fortran,lto,go,ada
Thread model: posix

The compilation stops right with the message=20

internal compiler error: in tsubst_pack_expansion, at cp/pt.c:12930

The closest string to match tsubst_pack_expansion I have on my system, is t=
hat
from the file cp-tree.h=20

Perhaps a duplicate of bug 104390 ?=
