it crashes because '%c' with 0 as parameter terminates the string before the
trailing \n
- when used without +msvcrt, we get very seldom traces, hence the buffer used
for the output is never flushed (it's flushed when a \n is sent) and overflows
at some point
- when used with +msvcrt, the buffer is flushed from time to time by the various
traces, hence we never see the overflow

I'll send a patch for the '%c' issue, and I'm still looking at the demangling issue.
