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 ‘p’ [-Wunused-parameter]
:~$ 

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