C source code

I just tried to compile the package quake3-1.36-13
on gcc-4.8 trunk dated 20120418 on an AMD x86_64 box.

The compiler said

code/botlib/be_ai_move.c: In function 'BotFuncBobStartEnd':
code/botlib/be_ai_move.c:2227:6: internal compiler error: in
remove_range_assertions, at tree-vrp.c:5937
 void BotFuncBobStartEnd(aas_reachability_t *reach, vec3_t start, vec3_t end,
vec3_t origin)
      ^
Please submit a full bug report,

Preprocessed source code attached. Flag -O2  required.

Reduced:
 % cat test.i
int a,b,c=0;
fn1 () {
  c = b >> 16;
  if (c > 32767)
    c = 0;
  a = b;
}
