reduced test case (provided by Craig Schroeder)

Running clang trunk on this C code:

k(0);k(a==8);int bar(){k(0);}

results in:

t7.c:1:3: error: expected parameter declarator
k(0);k(a==8);int bar(){k(0);}
  ^
t7.c:1:3: error: expected ')'
t7.c:1:2: note: to match this '('
k(0);k(a==8);int bar(){k(0);}
 ^
t7.c:1:1: warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
k(0);k(a==8);int bar(){k(0);}
^
