Summary: clang fails to reject invalid typeid expression and so
crashes later on
Product: clang
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
#include <typeinfo>
template<typename T> void foo() {};
int main() {
typeid(foo<int>);
}
The above is invalid (at least according to g++) but since clang accepts it
clang tries to generate the type's name using its name mangling logic and
therefore hits the following assert:
Assertion failed: (false && "Overloaded and dependent types shouldn't get to
name mangling"), function mangleType, file ItaniumMangle.cpp, line 1303.
g++'s output is:
typeinfo_assert.c++: In function ‘int main()’:
typeinfo_assert.c++:6: error: insufficient contextual information to determine
type
