Bug ID: 67784
Summary: Incorrect parsing when using declarations in for loops
and typedefs
Product: gcc
Version: 5.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jacques-henri.jourdan at inria dot Fr
Target Milestone: ---
The following code snippet does not parse correctly:
typedef int T;
void h() {
for(int T; ;)
if(1)
;
T *x;
x = 0;
}
However, this one does:
typedef int T;
void h() {
for(int T; ;)
if(1)
;
;
T *x;
x = 0;
}

--- Comment #1 from Jacques-Henri Jourdan <jacques-henri.jourdan at inria dot Fr> ---
My explanation of the problem is that the parser has to do a lookahead to make
sure that there is no "else" associated to the selection statement. However,
this lookahead is done in the wrong context, which make T look like a variable
(while it is actually a type name).
