Bug ID: 80449
Summary: ICE reporting failed partial class template
specialization class template argument deduction
Product: gcc
Version: 7.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ed at catmur dot co.uk
Target Milestone: ---
The following invalid code ICEs:
template<class S> struct C;
template<> struct C<int> { C(int, int) {} };
auto k = C{0, 0};
<source>:4:16: error: class template argument deduction failed:
auto k = C{0, 0};
^
<source>:4:16: internal compiler error: Segmentation fault
mmap: Cannot allocate memory
ICE also occurs if the primary template is complete and does not provide an
appropriate constructor:
template<class S> struct C {};
template<> struct C<int> { C(int, int) {} };
auto k = C{0, 0};
Looks similar to bug 79790.
