https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98687 --- Comment #6 from CVS Commits --- The master branch has been updated by Marek Polacek : https://gcc.gnu.org/g:d89b00c095e99cd5cb6d3e05f30d3a61fa592000 commit r11-6802-gd89b00c095e99cd5cb6d3e05f30d3a61fa592000 Author: Marek Polacek Date: Thu Jan 14 22:14:38 2021 -0500 c++: ICE with USING_DECL redeclaration [PR98687] My recent patch that introduced push_using_decl_bindings didn't handle USING_DECL redeclaration, therefore things broke. This patch amends that by breaking out a part of finish_nonmember_using_decl out to a separate function, push_using_decl_bindings, and calling it. It needs an overload, because name_lookup is only available inside of name-lookup.c. gcc/cp/ChangeLog: PR c++/98687 * name-lookup.c (push_using_decl_bindings): New, broken out of... (finish_nonmember_using_decl): ...here. * name-lookup.h (push_using_decl_bindings): Update declaration. * pt.c (tsubst_expr): Update the call to push_using_decl_bindings. gcc/testsuite/ChangeLog: PR c++/98687 * g++.dg/lookup/using64.C: New test. * g++.dg/lookup/using65.C: New test.

--- Comment #3 from David Binderman ---
Another test case:
void a();
namespace b {
using ::a;
}
namespace c {
template void a();
template void f(d, e) {
using b::a;
using c::a;
}
template void i(g j, h, e k) { f(j, k); }
} // namespace c
class l {
double m() const;
};
using c::i;
double l::m() const { i(0, 0, int()); }

--- Comment #2 from Marek Polacek ---
Adjusted test:
extern "C" namespace std {
double log1p(double);
}
namespace std_fallback {
template void log1p();
}
template struct log1p_impl {
static int run() {
using std::log1p;
using std_fallback::log1p;
return 0;
}
};
void log1p() { log1p_impl::run(); }
