  50 </I>There were a few segfaults in UnrealIRCd that I discovered on this box

  75 </I>&gt;<i>     This is puzzling; my gut instinct is to say that your libraries are
  76 </I>&gt;<i>broken.
  77 </I>&gt;<i>
  78 </I>&gt;<i>
  79 </I>&gt;<i>
  80 </I>I havent had any problems with the libraries with any other software.
  81
  82 &gt;&gt;<i>Let me know if theres any other info you need or if you want access to
  83 </I>&gt;&gt;<i>the machine to debug.
  84 </I>&gt;&gt;<i>
  85 </I>&gt;&gt;<i>
  86 </I>&gt;<i>
  87 </I>&gt;<i>     Access to the machine would be appreciated--I don't have any 64-bit
  88 </I>&gt;<i>machines handy.
  89 </I>&gt;<i>
  90 </I>&gt;<i>
  91 </I>&gt;<i>
  92 </I>I'll send you a private mail with the address and user/pw.
