Steps to reproduce:


Seg fault message below.  I suspect the same problem is also in cpr_darwin_timers_using_select.c

This timer implementation is currently stubbed out in the OSX version darwin_timers_using_select.  The resolution to this could be to remove this timer code for all platforms.

static cprRC_t addTimerToList (cpr_timer_t *cprTimerPtr, uint32_t duration, void *data) 
{
    // TODO([e-mail]): Put this back in when you figure out why it causes crashes
    return CPR_SUCCESS;

#if 0
