Summary: internal compiler error: verify_stmts failed / LHS in
noreturn call with pointer-to-never-returning-member
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: har...@gigawatt.nl
I came across this while reducing another testcase (which I'll report
separately):
$ cat bug.ii
template <class T>
static inline bool Dispatch (T* obj, bool (T::*func) ())
{
return (obj->*func) ();
}
class C
{
bool f (int);
bool g ();
};
bool C::f (int n)
{
bool b;
switch (n)
{
case 0:
b = Dispatch (this, &C::g);
case 1:
b = Dispatch (this, &C::g);
}
}
bool C::g ()
{
for (;;) { }
}
$ gcc -O bug.ii
bug.ii: In member function ‘bool C::f(int)’:
bug.ii:11:6: error: LHS in noreturn call
b_48 = C::g (D.2160_46);
bug.ii:11:6: internal compiler error: verify_stmts failed
