For recent gcc trunk, with this C++ source code:
template <int> class a;
template <int b> class c {
a<b> e;
void operator=(c d) { e = d; }
};
does this:
$ /home/dcb/gcc/results.20200709/bin/g++ -c -w bug629.cc
bug629.cc: In member function ‘void c<b>::operator=(c<b>)’:
bug629.cc:4:29: internal compiler error: Segmentation fault

Yet a couple of days ago, it was fine:
$ /home/dcb/gcc/results.20200707/bin/g++ -c -w bug629.cc
