           Summary: Function pointer types are wrongly compared
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]

clang blows up with the following program:
void (*f)(void);
void (*f)() = 0;


But gcc compiles happily. Also, in the draft for the standard (
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf
), it is said that (section 6.9.1 - Function definitions):

typedef int F(void); //type F is ‘‘function with no parameters
                     // returning int’’
// ...
int g() { /* ... */ } //RIGHT: g has type compatible with F

So I'm assuming it's a bug in clang.


The offending line is (I think) clang/lib/Sema/SemaDecl.cpp:401.
