Having tried two others I still find the system hanging at exactly the same place while building Perl, or more specifically when running perl harness at this point:- uni/chomp...................................ok uni/class................................... ie the uni/class test never finishes but CPU is at 100% whilst the test is running until it hangs. Can anyone suggest a reason for this? I've running various diagnostic tests on the memory but nothing shows up and I can't imagine what else to look at. -- John **= Email 2 ==========================** Date: Thu, 30 Dec 2004 10:24:28 -0500 From: lsunley at mb.sympatico.ca Subject: fork() FXSAVE and Pentium Pro Just in case anyone wants to know... the Pentium Pro CPU also SIGILL's with fork().

Oh well. Guess what the CPUs of my two machines are - an AMD K6-III and a Pentium Pro. I guess the K6-III haves the same as the K6-2 in that regard, or doesn't it?

I looked through the processor data sheet at http://www.amd.com and there is no mention of an FXSAVE instruction.

I just tried myself. initdb works fine, but postmaster terminates with SIGILL.
