I think this must be in testing. Maybe the "fail_reason" field is not initialized (or already freed) properly. That's the only reason the vsnprintf would crash... |
|
|
From testing_peergroup.c:923 pg_start_ctx->die_task = GNUNET_SCHEDULER_add_delayed (GNUNET_TIME_absolute_get_remaining (pg_start_ctx->timeout), &end_badly, "didn't generate all hostkeys within allowed startup time!"); All other calls give, and end_badly itself treats cls as a "struct PeerGroupStartupContext *", "char *" is given. |
