------- Additional Comments From eric.pouech@wanadoo.fr 2007-21-01 14:52 ------- 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.
