[Bug c/42667] New: internal compiler error: in insert_into_preds_of_block, at tree-ssa-pre.c:3146

Compile this with -O2 -m32:

extern int strlen(const char *);
void WriteTextDots(int len);

void OnDisplay(char * string)
{
   if(!string) string = "(none)";
   WriteTextDots(strlen(string));
}

Compile with -O2:
Only happens with -fno-builtin-strcpy
Seemingly related to Bug 42667.
Looks like there is a problem with implicit builtin function declarations and
the ternary operator : ?.
warning: incompatible implicit declaration of built-in function ‘strcpy'
