Summary: [9/10 Regression] ICE in make_decl_rtl, at
varasm.c:1344
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Changed between 20180513 and 20180527, at -O2+ :
$ cat z1.cc
template <int n> struct S
{
long c[n];
void f (S d)
{
for (int i = 2;; i++)
c[i] &= d.c[i];
}
};
template <int m> struct T:S<m/64>
{
void operator &= (T d)
{ this -> f (d); }
};
void g (T<192> &d)
{
T<192> v;
d &= v;
}
