More info on segfaults:
built perl on pclinuxos saw no segfaults during the build
Opened the syslog and boom here it is:

It looked like it built correctly from watching the build but if you
don't look in the syslog you will not know that they occured
Can some one have a look in their syslog after they just built perl to
see if it was clean?
I did the following:
tail -f /var/log/syslog
Yes it is syslog on pclinuxos and not sys.log
I did a test build and did get those segfaults in my log. There were 10
instances over about 0.3 seconds.
Mine look a little different. The log entries are in pairs. For example
(formatted):
May 8 15:43:37 frodo84 kernel: [4311687.668999] perl[23266]:
segfault at 7ffe87508ff8
ip 00000000004e5012
sp 00007ffe87509000 error 6 in perl[407000+22c000]
May 8 15:43:37 frodo84 kernel: [4311687.669009]
Code: 00 b8 04 69 64 00 48 0f 45 d0 89 ee bf 20 56 67 00 31 c0 e8 30
63 09 00 ba 16 87 c9 00 eb eb 66 0f 1f 84 00 00 00 00 00 41 56

64 48
I did not do an install for this test. It does not happen in the
Configure command so something in one of the Makefiles is causing it,
but I can't find a reference in the log.
