[Bug c++/13833] New: [3.4/3.5 regression] Conversion problem in template function

[bangerth at dealii dot org]

In this code 
--------------------- 
struct X { 
    template <typename T> 
    X & operator << (const T &t); 
    X & operator<< (int& (*p) (int&)); 
}; 
 
X x; 
 
template <int> void foo () { 
  x << (1 ? "ok" : "failed"); 
} 
 
template void foo<1>(); 
------------------------ 
 
we now get 
g/x> /home/bangerth/bin/gcc-3.5-pre/bin/c++ -c x.cc 
x.cc: In function `void foo()': 
x.cc:10: error: conditional expression between distinct pointer types `const 
char (*)[3]' and `const char (*)[7]' lacks a cast 
 
That sounds bogus to me, though I could be wrong. This is with present 
mainline and tree-ssa (don't have 3.4 checked out right now, but that 
is likely to be affected as well). 3.3 is ok, though. 
 
Note that the same doesn't happen if foo is not a template, which makes 
me even more suspicious.
