            Bug ID: 17059
           Summary: GDB crashes on setting breakpoint
           Product: gdb
           Version: 7.7
            Status: NEW
          Severity: normal
          Priority: P2
         Component: breakpoints
          Assignee: unassigned at sourceware dot org
          Reporter: ks132 at yandex dot ru

Gdb crashes with stack overflow when setting breakpoint on function
'f(param*)'.
If I add param struct definition at 1st line (remove comment), breakpoint works
as expected.

:~$ cat test.c 
//struct param {};

typedef struct param param;

void f(param* p) {}

int main() { f(0); return 0;}
:~$ 
:~$ 
:~$ g++ -Wall -Wextra -g test.c
test.c:5:6: warning: unused parameter âpâ [-Wunused-parameter]
:~$ 

:gdb$ gdb --args ./gdb --data-directory=`pwd`/data-directory -ex "b
'f(param*)'" ~/a.out
