Bug ID: 49759
Summary: [fuzz] ICE on invalid: __make_integer_seq with
inappropriate first argument assert-fails
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org

cat >test.cpp <<EOF
template <class> struct A;
struct S { __make_integer_seq<A, int, 42> m; };
S s;
EOF
clang++ -std=c++11 -c test.cpp
The symptom is an assert-fail, which means you need to compile Clang in "Debug"
mode (to enable assertions) in order to see this repro.
======
test.cpp:2:12: error: too many template arguments for class template 'A'
struct S { __make_integer_seq<A, int, 42> m; };
^
test.cpp:1:25: note: template is declared here
template <class> struct A;
~~~~~~~~~~~~~~~~ ^
Assertion failed: (!T->isDependentType() && "should not see dependent types
here"), function getTypeInfoImpl, file
tools/clang/include/clang/AST/TypeNodes.inc, line 70.
