[Bug c++/94426] [10 Regression] ICE in mangle_decl with -flto
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94426 --- Comment #7 from CVS Commits --- The master branch has been updated by Iain D Sandoe : https://gcc.gnu.org/g:b084efe3fcdfcf88e1703800b9b99347e89beefb commit r10-7761-gb084efe3fcdfcf88e1703800b9b99347e89beefb Author: Iain Sandoe Date: Thu Apr 16 21:13:51 2020 +0100 testsuite: Update pr94426-2 test to handle more targets [PR94426] The function (_Z4InitIN3VARIZ1qvEUlvE_EUlvE_EEbT_) that initializes VAR has changed siganture. It was was weak / comdat [Linux] or weak / global [Darwin] and now is text section local. So: test that the symbol exists, is spelled the way intended by the ABI mangling and is not weak (or global on Darwin). gcc/testsuite/ChangeLog: 2020-04-16 Iain Sandoe PR c++/94426 * g++.dg/cpp0x/lambda/pr94426-2.C: Adjust scan-asms to test for the change on more platforms.

Reduced testcase:
template using Void = void;
template bool Init (U);
template bool VAR = Init ([] {});
template
Void> Foo (T)
{}
void q ()
{
Foo ([] {});
}
bug.ii: At global scope:
bug.ii:5:38: internal compiler error: in mangle_decl, at cp/mangle.c:3907
5 | template bool VAR = Init ([] {});

Adjusted testcase that ICEs already starting with the r10-7243 commit, again
-O2 -flto:
template struct b { static constexpr int c = a; };
template using d = b;
template auto ad() -> decltype(0);
struct m { d())> e; };
struct n : m { typedef decltype(e) ab; };
template using aj = int;
class C { void q(); int bq; };
template using bz = typename by::template
bz;
namespace ca {
struct r { template using bz = cc; };
template using cd = bz;
namespace ce {
struct s { template s(bj); };
struct t { bool c; };
t ci(void *, s);
}
template aj cl;
template bool f;
template constexpr bool destructible = n::ab ::c;
template constexpr bool cp = destructible;
template constexpr bool cq = cp;
template constexpr bool copyable = cq;
template constexpr bool cr = copyable;
}
namespace cs {
using namespace ca;
namespace ce {
template using da = cy;
}
template using da = ce::da<>;
template
bool db = ca::ce::ci(nullptr, [](auto g) -> decltype(cl>>)
{}).c;
template constexpr bool dd = cr;
template constexpr bool de = dd;
template constexpr bool h = de;
template constexpr bool df = h;
template bool dj = db;
namespace ce {
template struct H;
}
template using dn = ce::H;
template constexpr bool i = df;
struct {
template
auto operator()(cx, j, cc, k) -> cd && dj, cc>>>
{ while (1); }
template
void operator()(l, cc p2, k u) { (*this)(0, 0, p2, u); }
} o;
}
int p;
void C::q() { cs::o(bq, p, [] {}); }
The difference from the #c0 testcase is:
-template using bz = typename by::bz;
+template using bz = typename by::template
bz;
