           Summary: Wrong parsing of record decls in parameters' lists
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: bagnara at cs.unipr.it
                CC: llvmbugs at cs.uiuc.edu


The following testcase shows that clang erroneously "believes" that the scope
of record declarations in parameters' lists extends beyond the block scope and
not inside the block, as the standard mandates.

$ cat bug.c

struct s { int x; };

void f(struct s { int y; }* v) {
}

void g(struct t { int x; } *v) {
  struct t { int y; };
}
$ clang bug.c
bug.c:4:15: error: redefinition of 's'
void f(struct s { int y; }* v) {
              ^
bug.c:2:8: note: previous definition is here
struct s { int x; };
       ^
bug.c:7:15: warning: declaration of 'struct t' will not be visible outside of
      this function
void g(struct t { int x; } *v) {
              ^

$ gcc -c -w bug.c
bug.c: In function 'g':
bug.c:8: error: redefinition of 'struct t'
