            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=x86_64-unknown-linux-gnu
--enable-gnu-unique-object --enable-vtable-verify --prefix=/usr
--mandir=/usr/share/man --infodir=/usr/share/info --libexecdir=/usr/lib64
--libdir=/usr/lib64 --enable-threads=posix --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=release
--disable-libstdcxx-pch --with-isl --with-linker-hash-style=gnu
--disable-sjlj-exceptions --disable-target-libiberty
--enable-languages=c,c++,objc,obj-c++,fortran,lto,go,ada
Thread model: posix

The compilation stops right with the message 

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 that
from the file cp-tree.h 

Perhaps a duplicate of bug 104390 ?
