'Up to 200' is limited by WineDbg

stack.c:
185  * Do a backtrace on the current thread
186  */
187 unsigned stack_fetch_frames(const CONTEXT* _ctx)

239         if (nf > 200 || !ret) break;

There is also:
dbg.tab.c:/* YYINITDEPTH -- initial size of the parser's stacks.  */
dbg.tab.c:#ifndef YYINITDEPTH
dbg.tab.c:# define YYINITDEPTH 200

However, I'm also curious by repeat of '__clone', I don't understand
this part, hopefully someone else can explain it ;-)
